In reply to Trangia:
> Whenever my niece travels to the USA on business the word Tehran sends their immigration officers ballistic, and she gets hauled off for interrogation. Twice she has been detained in a police cell overnight. They always apologise eventually and release her, but their record keeping is crap, because they seem incapable of checking back to her last entry into the US!
I get stopped every time I enter the USA too, and as a minimum usually have to spend 3 hours in their "interrogation suite". Sometimes longer.
They would never tell me why. But after the 4th time I had a slightly more friendly guy escorting me back to the main concourse and he said, "I'm not supposed to tell you but you have the same name and birthday as someone convicted of terrorist offences in the UK".
So I looked him up and found this:

How I've been into the US on both my passports several times, and each time I have my fingerprint taken and they have my picture and copies of both my passports...so why still stop me? As a technically sophisticated country, surely they can flag my passport numbers with a "that's not him" flag and cross-reference to my prints?
I've tried saying so a couple of times, and shown them my previous entry stamps, but all they say is "I can't discuss that sir, please come along with me" and shove me in the "black hole" for several more hours.
