A lot of people do immigrate by flying in and not leaving when their visa expires. It doesn't make for very spectacular news footage though. Not sure what the numbers are, but I used to work in restaurants with lots of people who were "undocumented" and they all came to the US via flight. The people crossing the border on foot are absolutely destitute and easy targets of animosity

And such a large number that it dwarfs temporary visitors?
