Earlier quoted context omitted.
Is a person with dual citizenship (U.S. + a non-NATO western-European country) eligible for these positions?
Most positions listed will require US Citizenship.
Thanks, but I've encountered a lot of ambiguity in policies regarding whether "US citizenship" means sole U.S. citizenship.
Is your actual criterion that a candidate needs to have a good chance of obtaining a permanent security clearance?
Having run the gauntlet once before, I know that dual-citizenship isn't necessarily a deal-breaker in the eyes of OPM. Or at least it wasn't about 7 years ago.
