My parent are non us citizents and I dont know what to input in the "tax filling" part of the fafsa

I’m a US citizen but my parents aren’t and they live in a foreign country. How do I know their tax filling status?

If they won’t file U.S IRS return…you put “will not file”. You will need to get a non-filers statement and on that it indicates reasons why. Yours will be because they live in a foreign country.

Are you doing the FAFSA NOW for fall 2018 enrollment and aid?

There should be a way to choose that they file a foreign tax return.
