The funny thing though is that there are no questions when you fly domestically in the US. That is just a normal flight with no questions etc (well except for the few times TSA chooses to run a secondary inspection at the gate). I have never understood the massive security theater when flying to the US from a foreign airport on a US carrier. When I flew into LAX from CDG on Air France it was pretty relaxed. The gate agent just asked me what I was doing in the US (studying) and wanted to see my visa and my I20. When she saw that she just handed me the customs declearation form and I94 and that was it.

Well I can understand people who choose other destinations than the US nowadays. If you need to apply for a visa you need to go to an interview where you (depending on your situation) may be asked questions like the police does. Here you also submit your 10 fingerprints. When you get to the airport you may be asken the same questions, but the theater does not stop there. At port of entry you again undergo an interview and again you submit your fingerprints and get your photo taken. The US government still does not know why the tourist numbers go down.... Well the reason is simply that they presume all foreigners are criminals who seek to harm the USA.

Edit:
The attitudes of the US government does not apply to Americans in general whom I find very friendly and including. When I was new here I really didn't have much contact with other people, then one day I heard a party and I just thought well the worst thing which can happen is a NO, so I knocked on the door and they say I could just come in. Now I hang out with them regulary and they are all very friendly and nice people. If just the US government would change their attitudes and act like ordinary Americans things would be much, much better.
