ISSA TS with Lifestyle Poly

I wanted to know if ISSA TS is transferrable if I am to work for a DoD contractor instead of an IC one? The process from start to finish was done by the customer (exactly 4 years) and now the position is not suitable for me anymore (OCONUS). I was wondering if other contractors are able to verify it in DISS or SC and that I can get it crossed over.

Thanks,

It really depends on the IC customer, and possibly the DOD one too.

I had a Background check done by DHS and it was in CVS and JPAS. But not SC.
