Is it possible to obtain top security clearance with your foreign parents/spouse?

You don't need your TS to apply to 35L. Noone on here can tell you if you'll be accepted to 35L, it's an application MOS. So get onto the IKN recruiting site and ask a 35L Recruiter, the only person who can answer your questions and stop your packet. Before you say, "I'm doing research" you're not because Noone on here is the subject matter expert so anything anyone says here is speculation. I've put about a dozen CI agents into the field. You need to ask this stuff to the CI Recruiter and the CI Propenent

The rules change often, but seeing as none of them are from countries of concern, I don't forsee a problem. Depending on the current rules, your wife may need to get a U.S. citizenship, but not necessarily.

It's possible but this is something you will need to work through with your S-2/G-2 offices to get done correctly. Nobody here will be able to give better information than them.

I just screened a Soldier who has the same situation. Only difference is he already had his TS granted and as a result he did not require a waiver for having parents in S. korea when he submitted his application on IKN. As I tell everyone who wants to go Lima, put in your packet and let the powers who have final say make that decision.

Just to be clear, I was referring to rules for going 35L change often. When I became an agent, you could not have an immediate family member as a foreign national.

I saw a guy get a TS who was foreign born to Somali parents and he was raised in Qatar. I can't imagine filling out that number of foreign contracts.

All you can do is submit the paper work and wait, I do not know how long it takes now but depending on the clearance you need could take 6 months or longer.
