Also, I was a part-time student for one semester in 2012 at a community college. I looked if I could get Lifetime Learning Credit, and it said that the following could NOT claim it on their taxes:
"You (or your spouse) were a nonresident alien for any part of 2011 and the nonresident alien did not elect to be treated as a resident alien for tax purposes."

I did not file taxes in 2011, and obviously, I was a nonresident alien since I had not filed for DACA or EAD then. Does this mean that I can not claim this credit? Or can I claim it now that I'm a legal alien authorized to work for tax purposes?
