That is called bigamy!
From what I understand, you can't marry anyone who is already married (unless they divorce their current partner or become a widow)
No you will not become a Mexican citizen but you will have Mexican recidency. Your fiancee can have the option to apply for citizenship later on if she wants.
He shouldn't, but he CAN do whatever he wants.
The requirements are the same as for two citizens; they will depend on the state and county where the couple wants to marry.
No. Neither will automatically become citizen of the other country.
yes he or she can marry in the U.S
Probably a ten-year wait if at all.
Lie about ur wife say she is mexican too
No. Immigrants must fulfill certain requirements to become Mexican nationals.
Most foreigners can obtain a Mexican passport if they move to Mexico with an immigrant visa and live there for four years (2 years if married to a Mexican citizen). Then one can apply for Mexican citizenship and passport.
No. first of all because when a person is already married cannot marry another, unless he first gets a divorce from 1st. spouse, after he is divorced he may marry but if its for the purpose of getting legal residency immigration law prohibits it.
yes
