ps wasn't going to post this as a separate answer because it's 10 years old and i had a local job offer, but i found getting permanent residence to be very easy (i had arrived on a tourist visa, which can be renewed for up to 6 months). i can't remember if having the job offer was critical (i think it was the other way round - i needed the residency because employment would have been illegal on a tourist visa), but what surprised me was the need to show evidence of education level, so bring some kind of certificate!
