easy get a couple thousand dollars together then pray to the god of plastic surgery. :) but in all seriousness my best guess would be that your planning to do something to either an ex or trick someone into doing something that they would normally never do to you or that person.
that alone breaks numerous laws and rules.think of it logically you could end up killing someone,getting someone wrongfully locked up or something far worse.not to mention the laws of free will, do unto others,the 3fold and numerous others which could come back and bite you where it hurts with jaws like a t-rex hopped up on PCP. XD my advise be happy.
This is most easily solved with plastic surgery. Fix what you feel will make you look better. To become Mexican you have to live there long enough to be considered a permanent resident/citizen, so research places in Mexico that you would like to live, and if you don't speak Spanish I suggest getting started.
