Prior UK and Ukrainian military service. Security clearance issue?

Hello all.

Prior service. 9 years British Recon, just under a year Ukrainian service mostly Recon.

Marrying an American, so I’ll get a green card. Considering the 18X pathway cos I’m fuckin’ institutionalised and civilian life is a no no for me.

Anyway, do you think my prior service could pose genuine issues getting the required security clearance? I’m trying to remain optimistic it will come from the POV of “western interests” but I’m going to be naturally bias.

Thanks all.
