A lot of these jobs require that you be a US Citizen in order to pass the background check to be granted a security clearance. There are lots of jobs posted at clearancejobs.com and other sites that reflect this need. It may take 6-9 months for that process to complete itself (or up to ~2 years in some cases) but once that gauntlet has been run, it becomes much easier the next time.
If you're a qualified networking or IT geek that meets those criteria, there are plenty of jobs available.

Some of these jobs are serious cash $119k+ ($10k/mo)
