I think most of the top government jobs are going to require clearance, which requires US citizenship. I really have no experience or advice with what you are asking, though. Maybe go the H-1B route, get permanent residency and try for citizenship? Try and give talks at conferences like blackhat and rsa? (I really have no idea and am just guessing).
