Being told the position I'm offered requires only a T3 investigation, not a security clearance

So is it better to withdraw and not submit my 86 in lieu of submitting and being deemed unsuitable? Again, even if I’m initially cleared to work, but in the end found unsuitable for the position, I will be let go. So it’s a gamble to take a chance walking away from a job in hopes if being retained for another.

Any suggestions on how I should approach? Thanks in advance

Let the Security Manager do their job and just go along.

You’re asking for career advice? That’s not what we are here for. We can’t tell you if changing jobs is worth the risk. We can’t tell you if you will clear this investigation. You need to sit down and make some decisions on your own.
