Deske, can't imagine why if you have a job in Europe you would consider it. Don't imagine for a moment you would get an upgrade here. It's way to early for them to even think about such a concept.
Expect the unexpected. Accom cheap at USD300-500 a month but not much of it up to western standards. Save? How much of what's left of $3000, after you have paid for food, beer, girls and a pad could possibly be called savings. The answer to the last question is better left off Pprune.
