Thanks for all the replies guys.
If I'm able to late-register for my Spanish birth certificate, then that will be the easiest route for citizenship for me. We'll see what happens with that.
In terms of employment:
-Pilot: A job in this field seems like a long shot seeing as how I still need all the other licenses and the number of opportunities are small.
-ATC: At least within Spain, looks like being an FAA ATC doesn't give you enough of an edge to land a job. EUROCONTROL might be a possibility but that's not what I really want to do.
-Airlines: Working for the airlines in terms of operations seems like my best bet to work in the aviation industry. I would love to do something equivalent to a dispatcher here in the States.
-Airport: Anyone know anything about Airport Management jobs?
