Hey other Squawk!
A friend of mine got his H1B visa denied a few weeks ago! He also applied for a pilot position, a flight school/charter place wanted him. The INS stated that the pilot profession does NOT qualify for this visa type (H1B).
I also tried (or am trying) this route. Unfortunately, I don't have a sponsor yet, but the news from my friend is grim. Apparently, the INS argues that a pilot position doesn't require a college degree (...and want do most airlines want in the US?- dop!) and the H1B visa requires a "specialty occupation" with a four college degree.
Very sad times ahead. If anyone has tried this route and succeeded please PM me.
