Adding mine. I traveled to US three times, each time the border check was unpleasant. I don't get it why they can't just do a passport check and be gone with it like the do in EU? What's the point of the questions, last time they event wanted me to show them my return airline tickets (why? If I wanted to stay illegally I could have created those easily). And the queues, after a long flight, the last thing you want it to stand in those long queues and waiting for hours to get to the hotel. BTW. I'm white, but from Central Europe (Poland) - but why would I want to stay illegally in SF or Dallas when there are cheaper places with more Poles.
