Braco! I come from Macedonia too and yeah I am quite familiar with the schemes and reasons people go and stay, I know a few folks who've immigrated that way as well. But I thought people in Serbia do that too, didnt know that its harder for them. In fact I've also met a few folks from Montenegro inside the US that clearly overstayed, but they were doing quite well, opened up a restaurant etc.
P.S. I go to Montenegro every summer I have a place there its amazing!
