Wow. I'm surprised. I could understand if you had been there for over a year and were just hiding out and keeping a low profile. But actually going in and out of the country? I think you're asking for serious trouble. One day they will catch you and probably ban you from entering Poland again. By the way, do you work there in Poland?
