Noncustodial Parent Taxes

So, I’m a Questbridge finalist, and every college that I have ranked is asking for my Noncustodial parent’s federal taxes.

Here is the problem: my noncustodial parent lives overseas…
I’ve looked into waiving the Noncustodial parent information, but that option is only for finalists who don’t have means of communication with their parent.

Does anyone know what I’m supposed to do?

Do you have a way to contact him? If yes, then ask for the income information.
