My wife is an Iranian national and American green card holder (we will be trying for naturalization soon). I am an American born citizen. Her parents are retirees in Iran, and never had anything to do with anything political, and neither has she. I am looking at some federal jobs (nothing to do with intelligence, military, etc.) and some of them require some sort of security clearance, even if it’s public trust or confidential.
Any idea of the highest clearance I would be able to get considering my wife? I just wanted to scope that out before I put in any effort re jobs. I otherwise have a squeaky clean record.
