You'll likely have to be careful with profiling here. You'll probably need to have documentation/proof that you ask this question to all candidates regardless of race or immigration status. And yes, that means you'll need to ask it to people that clearly aren't North Korean (though that maybe be a good thing in general as I'm sure the next step for the NK regime would be to pay people who are not Asian or who have American accents to do interviews if the practice became widespread)
