I have omitted one case: The two year requirement might also apply if the visitor is from a developing country and his skill is needed in that country, but there are very few European countries on that list.

We just sponsored an H-1B and a J1, and all I can say is to be careful about advice on forums. It's good for background, but get a _good_ immigration lawyer.
