I'd say go for it, but as rudestuff said you really need the consider the possible risks involved with the feds in the US. Flight instructing can be a rewarding and long-time career. I see both CAE and FTE Jerez are looking for instructors, and so are Lufthansa/Austrian Academy. It's also a nice way to network people and make you way up in the general aviation.
And I'd rather be flying hours, possible as PIC and be paid for doing it rather than sitting home to send CVs.
Anything that keeps you in the loop.
