Yeah, a lot of people who went to the US illegaly now own businesses. A highschool buddy went to drive trucks in like 2014, now has his own trucking company, several trucks, bunch of employees (Montenegrin and otherwise).

When I say semi-legally, there are people who do kind of get the green card through marriage, but it's fake marriages. A lot of truckers do it and it seems to be tolerated.

BTW apparently (I searched online) now people from Serbia also go to the US to work illegaly, but it's a recent trend, in Montenegro it was commonplace since at least 2010 and in Albania since the 90s.
