I'm unsure which visa will work for me as I'll be doing a 3 month (under 90 day) unpaid internship this summer. On the "Immigration Services Agency" website it says that if its an unpaid internship for less than 90 days you need a "Temporary Visitor status of residence" which, as a US citizen I don't need to apply for. However, the Ministry of Foreign Affairs has unpaid internships under cultural activities visas. I obviously don't want to show up in June and be denied or be sent home at some point during the summer. Thank you.
