News today that Trump plans to increase the minimum qualifying base salary for H1B and related visas to $130,000 per year.
While the exact amount may still change, the final value is likely to be over $100,000 and could practically end using H1Bs for US regional pilot recruitment. The median base salary for "Airline Pilots" hired using this visa category in FY2016 was $73,000.
It's unknown if E3 visas will be similarly restricted by the Executive Order.
