Jockflyer,
Sorry you feel that way. Most of us are not here on work visas, instead we are married to UK nationals. I don't know of any airlines that would apply for work visas. That is a long and lengthy process.
I gave up a great job to move here to be with my wife and it sure would be nice if we could both complete our dreams while living in the same country. Its not my wish to take jobs from UK citizens but I see no other way for me to complete my dream.
I was bumped out of my first flight instructor job by a foreign national, just because they had less time to build hours being on a 2 year visa. So it happens on both sides of the pond.
Good luck with your job hunt!
