What is "Foreign Tax Returns" ?

I am an international student and I applied to Rice. On my ESTHER account it says that I have to submit the “Foreign Tax Returns.” Is it basically the 2016/2017 tax return? Because in Romania we do not have those either. Please help me.

If you don’t have tax returns in your country, there is nothing to submit. Contact the financial aid offices at the colleges and universities on your list, and ask each of them what they would like you to send them because there are no tax returns in Romania.

They will most likely ask you to submit SOME evidence of your family’s income - whatever that is in Romania. You should have those documents ready.
