Not a stamp nor a sticker. It is a maybe 2" X 2" square paper with a few details like when you have to leave by. You are supposed to keep it to show with your passport in such circumstances where someone asks (no idea who, maybe the police?) and it is not asked for by passport control when you leave. They already know the details.
