He doesn't know that am here and doing some online/desk research for him
Why doesn't he know, that is, why haven't you told him?
If your boyfriend has passed his ATPL exams, I would assume that he has done his own research as to which training and licence he wants to obtain. There's no point obtaining a USA licence if you have no right to work there. If you want to convert a USA licence to a European licence, you need to add conversion costs. I am sure your boyfriend has done this already. Perhaps he has already read Pprune!!
