How can I find out where my teenage son can apply for financial aid to study in Spain?

Your bank account??

What nation do you live in, In the US I am not aware of any aid to study out side the US.

You could look into student exchange programs... or, if he is enrolled in a US university or college, they will often have study abroad programs through the university that he can use standard financial aid to cover.

Hi,

I know this answer is a bit late but might still be of help to those searching for answers... You can check GoAbroad.com's Financial Aid/Scholarships Abroad Directory.

Information on how to apply for a scholarship is a case to case basis so you should check the specific financial aid program.

Here's the Financial Aid Programs/Scholarships for Spain

Hope this helps,
