Also, as far as the eligibility to work thing goes, I've heard of people with Irish lineage getting dual citizenship, I don't know how recent the descendants were in those cases, but maybe if you've got some Euro blood coursing through your veins, you'll find a way in around that problem too.
As far as the working over there goes, I'd like to move back at some stage and work the North sea, but there's plenty of guys telling me not to waste my time at the minute, as there's tons of already qualified applicants lined up and ready to go, but the work just isn't there for them. In the mean time, I'll stick to building multi time here.
