Not far from where I live, I know a guy who overstaying his visa. I don't know how long, I don't know why and I see that he doesn't interact much with people when he leaves the house. I've always wondered how you can live peacefully, knowing that you live illegally. And if you have to be hospitalized, you have to show your passport. With the new banking rules, there is a risk that an account will be blocked and being overstayed, how could he do it...and much much more. I think one tries to avoid being seen around as much as possible. However, I will never understand why one would end up living like this.
