Quote: Would you happen to know if they'll refer back to the previous poly for any admissions if I take a new one. Seeing as they say, they'll keep it for that long for future background investigations; I'm leaning towards no, but I'm sure they could always access it.
I do not have any personal experience with the CBP. However, when it comes to the U.S. Intelligence Community, if you "fail" the pre-employment polygraph, which they consider part of the background investigation (BI), they keep the records FOREVER and you are BANNED FOR LIFE. I was told this by both the FBI (in writing) and by the CIA (over the phone) when I tried to reapply in 2017 after being rejected by both agencies some seven years prior. You can re-apply, sure, but when you get to the stage when they run your name and SSN in their own system, it is game over.
Here is my story regarding reapplying after a failed poly or BI in 2017.
Quote: My admissions were so minor and had no significance to me, that it wouldn't have even bothered me if I didn't say it. I feel like I failed because I gave them something to write.
Unfortunately, polygraphers love these "minor admissions". It gives them something to dig into. Check out
this thread from 2017 where the OP, fbx2, made a "minor admission" to spanking his cat, and was subsequently rejected for the job. He may have had bad luck and his polygrapher was a member of PETA! Next time, omit minor admissions, do not give the polygraphers ANY admissions.
Quote: If I do go through it again in two years, I really don't want to give the same admissions again, but I'm not sure if they refer back to it, and might just come back to me and say, "Well you said this over two years ago.".
This is exactly what they will do in the Intelligence Community. Actually, they will not let you get that far. After you reapply, and if they even consider your application again, they will run your name and info through their system, see that you were rejected before because of the poly/BI, and just reject you again. I was lucky to get another info session and interview with the CIA in 2017, seven years after my 2010 polygraph snafu that screwed up my whole security clearance career something rotten. Even with seven years passing, and having obtained TS/SCI from the Department of State, even though a DS&T office in the CIA wanted to hire me, the CIA Office of Security ran my info and saw my 2010 polygraph failures and had me rejected. The CIA recruitment office told me this over the phone, too bad I didn't get it in writing. See the same link I posted above.
