I suppose some people would say if you work illegally on an L you can just leave if you are stuck with a crappy school or university, but what about getting caught woking illegally?

Good point! I have no qualms about chancing it, in fact I relish doing so. I'm in a position to deal with the consequences and have no regrets afterwards. That I know for sure.

But I realize that it's not a good idea for many others to do as I do.
