Hey folks... There is absolutely nothing to worry about with regard to the exit visa. I used to live there for many years and I had no trouble at all getting the exit visa, for either myself or my mates there. Remember that a respectable and big employers like QR wouldn't get you in legal troubles unless you ask for it! Well, things may go wrong sometimes with some people! But if you dig deeper, there must have been something wrong as well that they've done. So just make sure that you don't walk in the dirt... Life then would be easy!
Good luck.
