Pilot Shortage Misnomer !
US Pilot shortage is more hype than fact. We train the highest number of pilots in the shortest period of time and supply them all over the world.
Currently, the mins have dropped to 250hrs at some regionals and it won't be long before the majors will be hiring 500hr guys.
Nevertheless, if push comes to shove , the H1 visa will be used to accomodate foreign pilots, who are currently working as Pt91/135 pilots with thousands of hours of experience.
