I’ve been on this blog for a couple of months now and from what some of us have been able to gather does not seem to be an order in which things are done. For instance, you noted that some people seem to have their poly/psyc done first, that does seem to happen based on some responses, but that was not the case in my situation. Mine was down last. No two timelines seem to be the same either, there are a variety of jobs at each of the three letter agencies and clearances take time and are also dependent on your life, what have you done, lived, traveled to, etc… all this stuff gets checked out and it takes time. I know my BI said I would meet with them for 2 hours, it took 5 hours, then I got follow up calls/texts needing documentation for things, mostly job info that they could not personally verify.
I applied in October of 2017, interviewed in March of 2018, CJO in Sept 2018, and submitted SF86 in October of 2018, and then BI in June 2019, and poly/psyc August 2019.
I have a decent amount of foreign travel and foreign contacts because of my discipline and grad school.
There’s also a backlog. So that will take time too…
Try to hang in there, your recruiter should be able to give you some info, but they aren’t always helpful. I was checking in about 1-2 months with my recruiter, but it would take a while to get a response from them… It does seem that the closer I am to being done with the process, the faster the recruiter returns my calls/emails. But, that can just be a coincidence.
