Plus, you know... Airplanes...
Exactly! You know how you get into a country? Get a tourist visa and overstay your welcome. I know quite a few middle-class people who have done that.
I believe that currently applies to the statistically largest group of illegal immigrants in the US
That's believable. It's just too easy.
Yup. In fact I know several Europeans who have done it. Which makes the racism of "illegals" = Mexicans specifically for some reason that much harsher.
You know, when I went to a US consulate to get my visa I observed some interviews while waiting in line. Interviewers seemed to ask more probing and sometimes humiliating questions to people who looked less white (and poorer). I get why they would do that to people in less qualified jobs, there is the idea that those are wanting to escape to a developed country riding on the dream that there they will get good jobs, but based on skin colour?
When it was my turn, the interviewer didn't even look at my papers, didn't ask any probing questions, he just looked at me, at my passport and approved my visa. It was a relief, since I had paid a hefty sum for it beforehand, but it left quite an impression.
