I would query NAS as I have an EASA ATPL and again wanted peoples input.
Presently, you are unprepared to attend an interview. NAS has no association whatsoever with pilot employment contracts with staffing agency OSM for onward, service provider, pilot rental to a Norwegian airline – “airline unemployment”.
I suggest you practice your response to the inevitable question from any US airline interview board, probably including a line captain, as to why, with an EASA license and living in Florida, you have not applied to OSM for Norwegian. Your response may determine your aviation career future.
