French scientist denied US entry after phone messages critical of Trump found

*those criteria, criterion being singular.

>more reliable indicator of low intelligence

I would add inability to use proper punctuation to that criteria.

these travels are scheduled months even years in advance depending on the field of study, nobody could have predicted how much worse second Trumps term would be. also other than travelling to somewhere where its bad much more reliable indicator of low intelligence are very confident statements outside of one's own depth.

These types of things are usually scheduled well in advance. Just one example, it is worth noting that I am not saying that this was the reason the scientist traveled to the United States, scientific centers with certain types of very expensive equipment usually rent it to projects from other scientific institutes and universities, sometimes with such high demand that you can wait years for it to be available for your project.

You sound like an internet addict who never lived real life. What the hell is with this logic?

I have no proof, this is anecdotal, but I suspect they used a forensic analysis tool like Cellebrite, GreyKey, or Magnet Axiom to extract all the device data and search it, which makes it a cakewalk to filter for keywords, images, files, and the like. cops use this shit all the time, as do their terrorist friends all around the world.

It should be common sense.

Yes, death threats and rape threats are a good reason why a visitor should not be admitted to the United States.

Restart your android before going through customs

Go to the US with a dedicated phone, just like to China.

Except nobody molested your phone.

Yeah but he can just say "hand over your unlocked phone or I will reject your entry" and then it's the same thing

If you use fingerprint or face scan to unlock your phone, they *can* compel you to unlock your phone.

If you use a PIN, they cannot.

Paving all of them over would be a huge endeavor. I hope Putins orange labrador doesn't take is as a challenge.

Eh, I think I might be turned off visiting ever again.

But think of the endless suburban car parks and Walmarts. Such culture.

Personally I'd like to visit the US for their national parks, or whatever is left after this administration policies.

I have to admit that ironically "Days Gone" made me fall in love with your nature.

You're not missing a fucking thing, buddy.

These guys are handing their phones over to show work itinerary in their emails amd the immigration officers are then going through all their other emails and messages.

Never, never, never, hand your unlocked phone over to an immigration officer. Print everything you need out before hand.

Well if you don't see a message from me after Saturday, you can assume the worst.

The cruelty is the point, so I imagine you would be detained and forcibly removed. They would make it as miserable for you as possible.

My entry to China was really easy. I'm very concerned about my return trip to the US. I have to come back at my home and family are there.. doors anyone know if I'm denied entity if I can just book and flight and leave? Why do I need to have the government deport off in rolling to go on my own?

That's not _only_ US either, Canada, Australia, Great Britain, China - all can coerce you into unlocking your devices and detain you if you refuse which is fucking crazy.

Never ever give them this right even if you trust the government as they'll make a redundant copy and government data security is such a joke you'll be 100% pwnd.

Make sure your laptop is encrypted and disable face unlock on your phone. They can detain you for 24h in most places (6h in US) and will tell you to buy a return ticket. Do not take the risk even if you have nothing to hide.

As a security expert - these laws are 100% authoritarian abuse. As if terrorists can't host their encrypted terrorist files offsite and pull them from public wifi when they enter the country. It's an absolutely joke.

I'm not quite sure I'd call that trivial, haha.

There's also the option of making a hidden partition or otherwise doing stenography within the device. I'm guessing for most travelers just pretty surface level hiding of things will be enough, though. TSA agents are not cybersecurity experts.

People already worried then. There was no need for the law to grand this power. We don't need laws if wo rely on people to be just.

Phone searches: not new. People being rejected at the border because of posts critical of the incoming president, yes, that is very much a new thing.

Would love to see some stories of people rejected at the border for criticism of Biden or Obama if you can find any.

The laws haven't changed. This didn't start three months ago.

This might be normal opsec for a foreign agent, but absolutely ridiculous to expect average people or some French doctor to adhere to.

The reality is this issue would never have happened just three months ago, and the reason it's happening now is fascism.

I think Europeans, coming from a sane place where border crossings are more of a formality than anything else, don't expect a plane to the US to be a time machine/teleporter to East Berlin.

This is completely unnecessary if you travel to a western democracy, like an EU country, Canada, Australia, etc. America is no longer part of that group though, sadly.

What if all my accounts are old and haven't been updated in a decade? That's kind of outrageous.

I mean, there could be situations where one doesn't have a choice. Definitely try and avoid it, though, and don't go for fun.

Elbows up buddy! 🍁

The answer is to stop visiting the US.

Not just the US government.

The issue is border control won't believe you don't have any social media accounts and might refuse entry.

don't do this. it's a waste of your time. if you're actually scared of the us government, the answer is to stop using social media

if we are poop buddies i will share my sardines with you

Freedom for me but not for thee

Wow, ok. You, guys (Americans), are royally fucked over there. Yet another reason not to visit the US ever.

Well it was limited to " the browns" before.

usa was always “Russia”. The difference is usa have a massive propaganda apparatus to make us think you are the goodies and who are the baddies

https://edition.cnn.com/2017/02/13/us/citizen-nasa-engineer-detained-at-border-trnd/index.html

2017? Maybe earlier?

>talent just being squandered and the world ending up with a lost decade.

Still better than the US having the next Oppenheimer

Once the funding dries up the talent will be forced to leave. The question is, is Europe prepared to take advantage? I'm not so sure- the worst outcome would be talent just being squandered and the world ending up with a lost decade.

Who would have thought. (Literally everyone)

You respect the honesty because it reveals people's character. And if a person thinks that Taylor Swift is an awful singer, then cool, you can agree or disagree.

But when it's honesty about contempt for your fellow man? A punch in the face is the only thing that works.

One thing authoritarian systems have in common is a permanent atmosphere of fear. Honesty is highly unwanted there, integrity will get you straight into trouble. Fascist systems are built on hypocrisy and fear.

Usually I respect the honesty more than the subterfuge.

But when it's Nazi's. Nope. Wouldn't piss on them if they were on fire.

"May I have your permission to search through your phone?"

"Yes."

I notice you asked for an explanation and then only sort-of read the first sentence.

No, I read the whole thing, fully. I just disagreed with your analogy, thought it was a bad one, too verbose and obfuscating of the subject being talked about. Also it didn't cover someone searching your belongings with/without your permission, the subject being talked about. Law officials have more legal leeway to detain you than they do to search your belongings without your permission, so your analogy doesn't work (especially when you throw in beatings into it).

Also, didn't think your last paragraph was legally accurate, but didn't want to bother arguing the point, since 'amendment > law > policy/rule' is a well-known given. I'm aware of the difference. When I asked my original question, it was to confirm if the border enforcement people were actually honoring the 4th amendment, or not, whatever their thought processes were.

I did appreciate you taking the time to reply (and civilly at that) though, thank you. P.S. I hope the tone of my reply wasn't too harsh, it wasn't meant to be rude, just straightforward.

Consent in a situation like this is difficult to establish, **to the point of it being pointless**.

Hard disagree.

Did they ask him if they could search and he said yes, or no? Or did they just take his device away from him and did a search without his permission?

Consenting to a search, or have one mandated by a judge's order, is one of the fundamental pillars of citizen rights and laws in this country.

Was it a legal or illegal search? That's not a pointless question to ask.

well its better than the button pressing me

that's just silly. you don't have to press a button

I just upvoted because everyone else wasn't. I actually don't like your comment.

I have a quote above. As SF said, agents who do that would be violating court rulings.

held that it is unconstitutional for US border officials to subject **visitors**' devices to forensic searches without individualized suspicion of criminal wrongdoing

It's not like the Bill of Rights doesn't apply to people with just visas either.

https://www.wgbh.org/news/local/2025-03-14/green-card-holder-from-new-hampshire-interrogated-at-logan-airport-detained

>“It was just said that his green card was flagged,” said Astrid Senior, his mother. She said she didn’t hear from her son directly until Tuesday, when she learned he’d been hospitalized.

>**Senior described Schmidt being “violently interrogated” at Logan Airport for hours, and being stripped naked, put in a cold shower by two officials, and being put back onto a chair.**

>**She said Schmidt told her immigration agents pressured him to give up his green card. She said he was placed on a mat in a bright room with other people at the airport, with little food or water, suffered sleep deprivation, and was denied access to his medication for anxiety and depression.**

>**“He hardly got anything to drink. And then he wasn’t feeling very well and he collapsed,” said Senior.**

>He was transported by ambulance to Mass General Hospital. He didn’t know it at the time, but he also had influenza.

>On Tuesday, Schmidt was transported to the regional headquarters for ICE in Burlington, Massachusetts, and then transferred to the Wyatt facility. The family, including his partner, who is a cardiologist in Nashua, have acquired attorneys and been working with the German consulate in hopes to have him released on bail.

>Schmidt and his mother moved to the U.S. in 2007, and received green cards in 2008. He moved from California to New Hampshire in 2022.

>Senior described her son as a hardworking electrical engineer with a partner and 8-year-old daughter who are both U.S. citizens.

>I mean they fucking tortured a white European green card holder recently.

What is this news? I haven't heard of that yet.

I'm just gonna go out on a limb here and say they're ignoring whatever court precedent actually exists at this point anyway.

Also, a phrase I've heard a lot "you can beat the charge but you can't beat the ride." Meaning, like Luigi Mangione, you can argue in court about illegal seizures *after* it has already happened. I'm guessing *most* border patrol agents just plan on losing court cases like this, because they know, in the moment, they can get away with it.

I mean they fucking tortured a white European green card holder recently.

My understanding is that any protections like that only apply to citizens while at the border and not foreigners looking to travel.

A 2-1 circuit split means that the 2 currently prevails, thus making border searching of electronics illegal unless you're within the 11th's jurisdiction (Florida, Georgia, Alabama, while the guy was arrested traveling to a Texas conference), no?

In 2014, the US Supreme Court issued its landmark ruling in Riley v. California, which held that law enforcement officials violated the Fourth Amendment when they searched an arrestee's cellphone without a warrant. The court explained, "Modern cell phones are not just another technological convenience. With all they contain and all they may reveal, they hold for many Americans 'the privacies of life.' The fact that technology now allows an individual to carry such information in his hand does not make the information any less worthy of the protection for which the Founders fought."[15]

>

In 2013, before Riley was decided, the Ninth Circuit court of appeals held that reasonable suspicion is required to subject a computer seized at the border to forensic examination. [...] In May of 2018, in U.S. v. Kolsuz, the Fourth Circuit Court of Appeals has held that it is unconstitutional for US border officials to subject visitors' devices to forensic searches without individualized suspicion of criminal wrongdoing.[22] Just five days later, in U.S. v. Touset, the Eleventh Circuit Court of Appeals split with the Fourth and Ninth Circuits, ruling that the Fourth Amendment does not require suspicion for forensic searches of electronic devices at the border.[23] The existence of a circuit split is one of the factors that the Supreme Court of the United States considers when deciding whether to grant review of a case.[24]

Since the PATRIOT Act *at least*, but possibly since Reagan's Executive Order 12333.

Looks like there is also a court case from 1977 that is related.

https://en.m.wikipedia.org/wiki/Border_search_exception

Every border patrol agent within 100 miles of any US border has this authority and has for a looooong fucking time.

It's honestly a little shocking this isn't more well known.

Since, like the moment I learned about the US Borders.

It's always been a thing, you see a lot of these in r/privacy and now c/pricacy

Only US Citizens can refuse the search and still enter* but their devices could still be confiscated.

*for now

That's forced. Since when was it a thing?

It’s “voluntary” in the sense that either you allow it or you don’t get into the country.

Was that explicitly said to him? Did they tell him that if he refused the inspection that he would be denied entry?

BTW, what you described is a mandatory inspection.

~This~ ~comment~ ~is~ ~licensed~ ~under~ ~CC~ ~BY-NC-SA~ ~4.0~

It's "voluntary" in the sense that either you allow it or you don't get into the country.

Consent in a situation like this is difficult to establish, to the point of it being pointless. Your comment implies to me that you think if the person said "OK" to a search request then whatever happened next is their own fault.

Consider just the situation where you're in the immigration line and two uniformed officers walk up to you and say, "please come with us." If you go with them, is that voluntary? If you say "yes" I just think "voluntary" doesn't hold much meaning. What happens if you don't volunteer to go with them? Surely, they say, "come with us now or you'll be arrested." And if you don't volunteer at that point, they'll physically restrain you and take you away.

Since most people are able to understand the subtext of the situation, they're able to tell that, "please come with us" actually means "you are required to come with us now. You may either walk of your own accord, or we will take you captive and punish you beyond whatever we initially intended." So, there's not any consent happening. Just deciding whether being beaten and dragged away in public would be helpful to you, and in many cases it is not.

You might be confusing US law around unlawful search and seizure with US law around border crossings. While the ACLU's position is that the 4th amendment trumps CBP, CBP's position is that it does not and that you cannot stop them.

WTF is a voluntary search?

"Attention all flight passengers. This is ICE on the speaker. If you want to be searched, please raise your hand and we will get to you shortly."

i just downvoted because everyone else was doing it. I actually like your comment



Coconut

Pineapple

They could always do this before, it was jsut that previous administrations weren't this insane to actually do it.

Thanks. It's fucking wild the things we have to be concerned about in this upside down timeline.

>They cannot prevent you from entering the country.

Only applies to US citizens. Any non-citizen, including Permanent Residents (aka: Green Card holders), could be denied entry.

The US Government cannot deny US Citizens from entering the US.* However, they can (and mostly likely will) seize all your belongings and detain you for up to 48 hours. So its best to wipe your devices before crossing the border (both ways). They *can* deny permanent residents (aka: green card holders) from entry.

*for now

But my real advice is: Unless you are intending to migrate permanently, do not cross the US borders (neither in nor out) under the current administration.

They could try. They can compel you to open it with Face ID or fingerprint. If that’s turned off they cannot compel you to disclose your passcode. They can seize your phone. They cannot prevent you from entering the country.

They’re probably only going to do it with some kind of suspicion. But that suspicion could be the border protection officer is having a bad day.

John Oliver? Is it really you?

people can make social media accounts full of soft core rat erotica just for travel purposes.

I mean, you might fool them. But its best to just backup everything to a Non-US cloud provider in an encrypted format, and wipe the device before leaving. I wouldn't rely on the "multi-user" trick. Who knows what forensics tools they have.

2001.

I've got old phones that I've been considering for this use.

They both still work, minus the cellular data. So I'm having a tough time deciding between making my actual phone squeaky clean, or using the old ones have making it a *removed* to get home from the airport with no internet to call an uber/friend/deal with airline shenanigans.

Yeah, of course. The patriot act was already written way before 9/11, it was a wishlist and they only needed the right excuse to pass it. It's something they'd always wanted to begin with (both Republicans and Democrats), and it's politically not possible to repeal.

>Yep, 12 years of Democrats in charge and none of them did anything to reign in this whole apparatus

Its hard to actually repeal it. Any politician, republican, democrat, independent, whatever, who does so, and then a terrorist attack happens, they take the blame. That's why nobody tries. Its not an excuse tho, its just an explanation.

Yep, 12 years of Democrats in charge and none of them did anything to reign in this whole apparatus that could easily be abused by an autocrat. Now Trump has a turnkey surveillance state that can be turned on anyone in the country. All your internet traffic, current location, licence plate readers, face recognition, etc. It was all created to alternately catch terrorists or pedophiles, and now Trump is going to use it against anyone he doesn't like.

And it's not like nobody was warned, there was plenty of dissent about the patriot act from experts and the people, but politicians were just like 'don't worry, it'll only be used against terrorists'. Guess what, everyone's going to be deemed a terrorist now. They're trying to charge Luigi with terrorism already (and those are state charges in a Democratic state).

Definitely.

As a Latin American, the US is the very last county I want to visit on the entire continent. Literally the only thing that I kind of want to see there is the Lego store in NYC.

I've been very purposefully avoiding the US ever since the Patriot Act exactly because it became possible for the TSA to riffle through your electronics (even confiscate them) and do this kind of shit.

Then on top of that festering pit of autocracy which, by the way, nobody reversed in all this time, Trump added the risk of ICE detention and "free trip to El Salvador (to go check a mega prison there)".

or avoid going to america

ive seen people buy budget/used phones and leave thier main ones at home.

Since when did travel to the US become worse than to Russia? This is shocking...

Here's how the borders work:

"Sir/Ma'am, please unlock your device"

"No"

"Entry Denied"

---

(Except for US Citizens, they cannot be denied entry* even if they refuse to unlock their device, however, their devices could be confiscated

*for now)

IIRC they can compel you to unlock your phone. Or just deny you entry if you don't. It's best to make sure you travel with a 'clean' phone and PC, border patrol got ridiculous powers in the patriot act and nobody's ever rolled any of it back despite decades of abuses.

They can still make your life difficult though. I think the better option is don't fly into or through US territory if you can help it.

Get a burner for ANY international travel.

Consider it an *insurance* expense as a part of the trip.

They will also ask you for your password for online accounts and refuse entry if you don't.

And as we have all seen recently that does not necessarily mean "next flight home".

Just don't come here unless you have to. And get a burner if you do come.

If you have an android device, setup a second user account with nothing on it and use that when going through customs.

How’d they get into his phone? Face or fingerprint?

I was looking for this as well. It seems like a rather important piece of info for the article to leave out.

Years ago they would already ask for social media accounts and email address on US visa forms, it was creepy back them , scary now.

So, what if I as an american, travel to canada. On my re-entry, am i going to get my phone searched for anti-maga stuff?

Nazis are Nazis. Ask the people in that El Salvadoran prison if the boots forcing their necks down look like 40s or 2020s Nazis. Their agony is your answer.

It's important to distinguish the two. One was 85 years ago, the other is today... there might be other differences but can't think of any right now.

Why does that matter? They're both Nazis.

Yeah, but when you say "The Nazis literally did this with a law" it's not entirely clear if you mean the German Nazis from the 1940s or the American Nazis from the 2020s

Nazis are Nazis, the rest is semantics.

The Magas

the scientists were smart enough to flee Germany or places that nazis occupied. i see this going to happen with USa if not already, US already has a problem with shortages in some areas of stem. its a complex set of problems all around, this latest fiasco just adds into it.

Yup. "But we're not there yet", so they say. "Too soon to act rashly".

**'First they started mass deportations, but it wasn't a corrupt system yet, so we did not act.**

**Then they started refusing people who were critical of them, but it wasn't a corrupt system yet, so we did not act.**

**Then they started blatantly taking money from the poor and give it to the rich, but it wasn't a corrupt system yet, so we did not act.**

**Finally they fully took over the nation, but by then all the people who would have acted were already gone and dealt with.'**

Not all, but the gist of it. Thankfully some bubbles of resistance are starting to form in the US, but the main people who were elected to uphold the law and fight this democraticly are already bribed or blackmailed, so it's in great part up to the people, and whatever stance the army ends up taking when they are forced to choose between loyalty to the constitution, or an individual.

Might as well start wearing red triangles now🔻

Please don't say "Nazis". Like, which Nazis, the 1940s German ones or 2025 American ones? It's confusing. Please be clear next time you talk about them.

Always has been

Actual TDS. In that TDS is anyone who likes that fascist.

Republicans are really mad that reality has a left wing bias

My negative opinion predates the Trump administration. I never liked how they speak so confidently with limited and unsubstantiated evidence.

"The most useless creature on earth, directly followed by the second most useless, the journalist" one of my chemistry profs (a highly respected authority within the chemical community) used to say about politicians. A slightly extreme opinion, IMO, but he predicted several upcoming "scandals" caused by the press' and politicians' complete ignorance of chemistry and inability to think scientifically. His predictions turned out to be 100% right.

I fucking wonder why... Surely it's not the outright hostility towards them by this administration

Yeah I've been waiting for someone in academia to piss Trump off enough for him to go full-on Pol Pot...

Dictators hate intellectuals.

I don't even have to name any specific one, its a trend across all dictatorships.

Studies have consistwntly shown that the more education one gets, the more their political view skews left. It explains why colleges, staffed and managed by PhDs, tend to be left-wing. That's why the Conservative Propaganda Machine has to constantly attack education.

How strange that all the people who think don't like Trump?

or one that contradicts him, aka fauci.

There tends to be a general distaste toward politicians in general among the scientific community.

The Nazis literally did this with a law. They made it illegal to be critical of the party. Fuck the alarm, we've already been had.

Translation: if you're going to the US you might have to immediately find a flight back because their government might go through your phone and find out that you rightfully criticised their great orange leader. Glad I managed to visit before, America can go and choke on their aspirations.

Sounds like a case of “MAGA snowflake syndrome” smh

What? A scientist who is critical of Trump?? How can that be???

Amazing to think that they criticised "freedom of speech" in Europe

Funny that the US has become more like Russia since Trump was elected.

How’d they get into his phone? Face or fingerprint?

Make sure you turn off biometrics before traveling. They can’t force you to disclose a passcode.

EDIT: Actually, if you have to travel to the USA, wipe your phone before you leave.

The US has turned in Russia for real. Russians were checking phones at the border when the war started.

I told my wife before I could never go to the US because of the stuff I write online, now I'm sure of it

Honestly, dude probably dodged a bullet. Stay away from our shit hole country

Travel advise: prepare for a trip to the US like you'd prepare for a trip to Russia or China. (Note: being an anarchist who thinks Putin, Xi and Trump don't deserve a separate rope for each, I wouldn't consider a visit.)

Don't bring your real computing device. Bring an empty device from which you can VPN to a system that actually has your data.

If you need to bring an encrypted device, consider the possibility that authorities will attempt to coerce you into unlocking it (and will cause you great disruption and indignity if you won't). You might be safer bringing a concealed + encrypted microSD card and a device loaded with an OS intended to be searched. If the data matters, make sure you cannot unlock your device under coercion.

(Trivial method: send your friend in the US a snailmail letter. Ask them to keep the letter until your arrival. Into the letter, steganographically embed the OTP key material to obtain the passphrase to decrypt your device. Now to decrypt the device, three things will be needed: your cooperation and knowledge, the device, and the letter. And you can deny that the letter contains anything.)

*Edit: upgraded advise - mail your local contact an encrypted MicroSD card. Cross the border with a Raspberry Pi in factory packaging, or buy it locally (they're still permitted, despite their widespread use by anarchists).*

Fuck this shitty ass country.

I am going to die in a concentration camp before 2028

Haha, I'll never get into the USA. Trump is a snowflake melted on a turd and he can fuck a melon.

All countries should advise their citizens against travelling to the USA.

Edit: fixed typo.

Hey, that's a good thing in my book, I guess.

Same way as America prospered with talent fleeing a corrupt Europe in the past, now Europe can get that lost talent back from a corrupt America. The more they feel unwelcome and undervalued the more they will flock or stay wherever their talent can flourish and advance our progress as a society.

No complaints from me on that. 🤷‍♂️

Would be helpful if we could see those messages so we can form an opinion.

Fucking hell. Freedom of speech isn't a thing anymore and all those shitheads who were crying about simply being called out for saying things are fine with the government punishing people for saying things.

I wonder how they search it. I doubt they manually read every fucking text message in all apps, so I guess they search for keywords or something.

So, let's say someone wanted to get someone in trouble, they could write them an email with some "incriminating" white text on white background and have them stopped by the thought police at the border.

It would be funny if they stopped some Canadian Mexican returning from Cancun and found shittalk about Trump on his phone.

Btw. Does anyone have Ted Cruz's email address?

I have a burner but it seems like you need to create social media accounts filled with non political content and keep them updated so they don't look fake. Anyone know how to automate this?

Freedom of speech, eh? Guess I'm banned if they find out about this account or my Bluesky account.

immigration officers at an airport searched his phone

There's no mention in the article if this search was voluntary, or not.

Edit: For the downvoters, please point out where I was wrong; I'd honestly really like to know if it was voluntary or not.

~This~ ~comment~ ~is~ ~licensed~ ~under~ ~CC~ ~BY-NC-SA~ ~4.0~

The USA has no place criticising the actions of other countries. Never has.

I seriously doubt the intelligence of anyone still traveling to the USA. I hope whatever project he is working on is not critical.

"Freedom of speech."

Welcome to Trumps America.

Where everything that Trump doesnt like, or is legitimately critical of him, or is just an opinion that Republicans don't like.. is Terrorism.

Seems an awful lot like that oppressive government tyranny the ammosexuals were feverishly polishing their rifle barrels to, doesnt it? I wonder why they are all so suspiciously silent! /s

So people these days still not understand that border crossing are a sensitive location?

Like, literally, anywhere you go, the first thing you should do before leaving is encrypt and reinstall / factory reset (which should delete all encryption keys to the old data) the devices. And if you have very sensitive stuff, use a disk overwrite program, and for phones start recording a video with the phone aimed at like a wall (and turn off the audio recording). Leave it recording overnight and it should fill up your phone. Use 4K recording to fill the storage faster. Then just wipe the phone again. Now, DONT DOWNLOAD ANYTHING THAT COULD BE CONSIDERED SENSITIVE. Load the phone with innocuous things like pet photos, nature, etc... and act like a "normie". Don't have anything critical of any politician, especially not of the country you're visiting, nor of its allies. Its best to not have any social media apps, preferrably, you should never post things under your name, but if you already did have such accounts, delete them.

If they ask you "Do you have any social media accounts" you say "I don't recall having any" or "I don't think so" and "I'm not the type of person to use social media". Or alternatively, you can have a social media account that have *only* non-political posts, and show then that.

Edit: To be clear, don't travel to the US. But this should be how you prepare for border crossings, even if it isn't the US.
