I go to a College in Mexico and doesn't has EIN-1

You can use the Federal School Code in the link below.  If your school is approved you will find its code to use when you file your tax return.

It doesn't appears on the list, what can I do?

Not much - that means you cannot use the education expenses for tax benefits.

And do I need to delete information about college?

Yes, you are not required to enter it.

I receive $9500 per year and the federal due is $1342, is that right? I thought it was the 10%
