Why would you want a FAA PPL?
What would it do for you?
Are you an EASA Flight Instructor in Dublin?
If you are, why not just go get an EASA (f) ATPL as your next move.
I think everybody should start flying in the United States.
I believe that every career should have a FAA PPL and 200 hours total time, and 100 PIC.
Then you can decide if you want to go the American or European route.
