Yeah I did it back in the day (kinda). I just went through with converting to a U.S. PPL and then doing the Single Commercial, Multi Commercial and Instrument Rating flight tests.
Much easier to get a job then get the U.S. ATP later on....Then they changed the rules.
I was having trouble getting full time employment on a twin and got a much needed jab of experience flying over there. Most days I wish I wouldn't have left!
