Department of State Internships

Looking for people who have either applied or completed a DoS internship to answer some questions!

I’m currently a freshman, and have just started looking into DoS internships. I completed the National Security Language Initiative for Youth (Persian in Tajikistan) scholarship a few years ago, and I would really like to return to Tajikistan. The DoS app is currently closed so I can’t see what’s on it right now. Basically I’m wondering if you get to choose the location you’re sent to, or if you just apply to a particular office and they tell you where you’re going? Would also appreciate any other info about the contents of the app.

Also kinda related, what do they mean by 60 credit hours as a requirement to apply? I don’t go to college in the US so I’m unclear about how long I need to be in college before I apply.

Thanks!
