I wonder if the US would accept me as a refugee.

Only if you come in illegally from south of the border and speak Spanish, otherwise you'll be sent back.

I've thought about emmigrating to Mexico and becoming a citizen and then illegally coming back to America to work.

I doubt I'd be detected and I could opt out of taxes (does the IRS ever try to claim back taxes from illegal immigrants?).
