Okay, then this DS-160 form you have to submit before traveling sounds like the biggest obstacle. Most questions are basic stuff but there are security related Yes/No questions. Were you ever involved in terrorist acts etc. yet also were you ever a drug addict, ever sentenced to a penalty etc. which we have to assume that through the surveillance (they had even the cell phone tapped of German chancellor Angela Merkel, among others) they will know the answers beforehand even when the country of origin doesn't give them out officially unless in some strict cases, and act more as a check whether you're honest? But as this form gets checked and approved or declined before the flight, one might just try his/her luck
It's mostly an idiot test. They give a similar multiple choice test over here when applying for a gun permit. Just answer honestly and don't incriminate yourself. They asked me if I'd ever smoked weed when I applied for that. I'm an obvious pot head but there was no record of such so I answered no. Gave the same answer for "Have you ever been addicted to any substance like opioids?".
Just use common sense.
Just know from a Mexican girl who wanted to visit a family member in the states, and she had a history of mental illness and was in psychiatry multiple times. She gave the 'right' answers and got her visa approved.
Mental illness doesn't disqualify you from entering. If there are records saying you've been committed for violent acts you might want to answer honestly but most things related to medical stuff are private information that you don't have to admit to. Getting a Visa isn't really hard. America has the most lax immigration policy in the entire world. I'm serious we'll take in anybody. We might not let you become a citizen but getting into the country legally or illegally isn't that hard.
Crazy fact about the x-ray machines. Recently noticed that they now use these 'nude scanners' in Amsterdam too. Don't know if they work with classical x-ray but seems like the days of just stashing some drugs into the underwear and make sure not to have any remaining metal pieces but even if the detector warned, they'd just manually scan again and wave through but Amsterdam's new terminal looked tight last time.
I think it's more like a CT scan than an x-ray. If they see anything funny they will take a closer look. I once forgot to take off my belt and was greeted by a lot of security on the other side of the machine. Once they realized my mistake I was quickly waved by. Attempting to stash something up your butt or in your underwear is the worst place to put something. You're better off just putting it in your luggage. I prefer using my carry-on because I always have access to it. The only time my luggage was searched (that I know of) I didn't even have anything illegal in it. They just pulled it randomly or something in there tripped their scanners. They aren't really concerned about personal amounts of drugs. They're looking for bombs, weapons, and large amounts of drugs.
Same deal with the dogs when you see them at airports or places like Disney world. They're sniffing for bombs not drugs. America is pretty lax on allowing small amounts of drugs in. It isn't Australia, China, or Japan where they're looking hard for them. It's a security theater in US airports. The people doing security are being paid minimum wage and most of them give no fucks. If you're someone interesting that the people way up the chain are concerned about they're probably waiting for you before you even arrive at the airport.
They do look more closely when things out of the ordinary happen. I once flew with my family on vacation. One member of the family had the wrong last name on their ticket. They flew down and were waved right through all security check points. On the way back we discovered the error and she had to get the details on the ticket changed. They looked her over hard when you came back through security. She had her hands tested for bomb residue and everything. Meanwhile I'm waiting on the other side of the checkpoint with a wallet full of LSD, several capsules of MDMA and half a joint in my carry-on, all while being very obviously hung over from a night of candy flipping. I was reading Ted Kazinski's latest book while waiting for her.
They probably know I'm half crazy, use drugs, and don't like the Government but they also know I'm poor and not violent. So they don't care.
