I started mine 14 months ago and 2 polys later, I'm still waiting. No word for 6 months after the 2nd poly. Anyone have any idea how long?
Once you get through the polys, NSA will direct the
DSS/DoD to start the TS background investigation.
For the TS, it is taking at least a year; once that is
completed, then your case still has to go through NSA
adjudication. Adjudication can also take up to a year,
or more. Also, NSA is getting very anal, so don't hold
your breath, about getting in. I waited two years, then
went with a different Intel agency. Good luck !
