Yep I was supposed to go to the US for a month in December of 2016 to meet my now ex gf and bf. When I'd gone through control, they wanted a second look at my passport. Then they stood around discussing my passport, and pulled me off to the side for individual interview. Tons of other people walked past me without being put through special control so the only reason I can see that they would want to investigate me further after seeing my SWEDISH PASSPORT (hint hint: Swedes don't normally illegally immigrate to the us because us healthcare and job market is shit compared to ours) is that my name is male and my legal sex is female.
They interrogated me, lied to me for 4 hours and ruined some of my belongings. They had found one tiny excuse to use to argue for their claim that I was trying to immigrate illegally, and they skewed anything I said to try to fit that claim. They even made false information reports/records of the event by claiming I had answered "yes" to the question "are you a lawful resident of the united states?". They rushed and pushed me to sign the paperwork that sneakily claims this without reading it thoroughly, by claiming that my plane back to sweden was about to leave and I had to be quick.
They isolated me and refused to let me reply to my mother's worried messages. On the 9 hour plane back home I had to sit and stare at a phone that was blown up with heartbreakingly worried messages from my family, without being able to reply. They thought I had been kidnapped and begged me to answer just to show that I was okay.
The police used the wrong pronouns and asked very odd questions regarding me being transgender.
The whole event had me an emotional wreck for a full month afterwards, I had moments of physical panic where my heart would race and it would be difficult to breathe and I couldn't figure out why. For this reason I am not going to the US anytime soon.
A fan told me they had a friend who got stuck in a similar scenario, except they ended up in PRISON.
I do not view the US as a place that's safe to travel to or through for trans people.
