Thanks for your comment, understood, would an ATO want to sponsor me if the plan was to work for them for a bit and then leave them to pursue ATPL studies? Or do I not tell them that part? The main concern is going ahead with said plan, doing my FAA ATPL and finding out that I am being deported, left with a relatively useless ATPL. I'm aware that in life and your career it is necessary to take risks but it could be a very costly mistake.
What do you think?
