Once again, garry's right. I can't access the ind pages, but it seems to be 4 years on a continuous work permit, but not necessarily with the same company. I take it that it means that you'll have to be hired by a new firm without an employment gap. To my defense, I positively remember getting the info about 4 years with the same company from many expats and my firm as well (so maybe they were just having one on me at the time, although it seemed believable since another Aermican at the company stayed until the 4 year time came due, and then she jumped).
