Can you apply to positions that require a clearance while already under a current sponsorship? Polygraph doubts

Long story short, I am under a contractor under the NSA. I’m going back for my fourth polygraph. I do not have much confidence this will go the right way for me. I mean, ill keep going back if they offer it but I dont want all my eggs in one basket. The anticipation of me being able to change my life being dangled by this test is just not stable enough for me. I have nothing to hide and made it very clear. I stuck with every answer on my form and still be questioned like I am drastically failing. There is other opportunities that sponsor for a clearance that do not require a polygraph. If you were me, what would you do?

  1. Just wait for things to play out? My next polygraph is in a couple weeks. See what the polygrapher says if I failed or I passed then start applying elsewhere?
  2. If one investigation doesn’t interfere with the other, apply to the other positions now.

I had alot of people say to wait and just let it play out. But again, I’ve seen people be told that they had to wait 9-10 months just to be told they failed suitability due to the polygraph. There is no way I am going to wait another year for that type of probable ending. But yeah, what would you do?

I wish I fully knew what I was getting into. If I knew what a polygraph was before starting, I would’ve skipped out on this.
