I don’t know much about deportation law, but I know that I was dating a Brit and due to gay marriage not being legal in the states she would never be able to get a marriage visa and since she’s British it’s pretty hard to get into the visa lottery, so we’d have to wait until we just worked and had enough money that she could essentially BUY her way into the country. At that point, I was more than a bit frustrated with the US immigration system.
