Situation:
I am a born U.S. citizen. My wife is an illegal immigrant. She came here legally with her parents when she was about 8. Her visa expired before she was eighteen and she has been living here illegally ever since. She is now almost 20. We now know that she can stay in the U.S. if we get a lawyer to help us get her resident status. We are both still students, my "estimated family contribution" is 0 for the FAFSA, I should be eligible for food stamps, and she is unable to work for the next few years for obvious reasons.

Question:
Will I still be eligible for those two specific financial aid programs after we start the process of naturalizing my wife?
