I read your other post where you wrote that you were rejected from the NSA based on a polygraph admission. Even though they say you can reapply in one year, the truth is that you will just get rejected again.
Once you fail the poly or background check from the U.S. Intelligence Community, you are banned for life. Yep. Try to find anyone that failed a poly and got rehired later by the same agency . . . you won’t find anyone.
If your new job is on an NSA contract and you have to go through the NSA security clearance and polygraph again, you will be immediately rejected once NSA runs your name and SSN through a database and finds out they rejected you before.
