No, it is very difficult for Mexicans to become American citizens
Not automatically. They have to apply for a green card and then apply for Naturalization.
no they do not the Mexican instead becomes an American citizen
No.
Yes.
They will become an American citizen
The Mexican must apply for Resident Status and after 3 years of being a Resident Alien they can apply for Citizenship.
if an illegal Mexican marries an American they can't go back into Mexico and reenter the United States legally. They can only go to Mexico and reenter legally if they have been granted a Visa.
i don't think so.
Not automatically.
I GOT PAPERS AND I WANNA GET MARRIED TO A MEXICAN GIRL WHO DONT HAVE ANY PAPER.WHAT DOES SHE NEED TO GET MARRIED TO ME AND CROSS TO ARIZONA
A foreigner who marries a Mexican doesn't automatically get Mexican nationality, but they can apply for Mexican nationality after only 2 years instead of waiting longer. For example, a foreigner (not married to a Mexican) who applies for Mexican nationality on the basis of Mexican residence has to wait 5 years.
If a Mexican man marries an American girl he can apply for a green card, which gives him legal residency. Over time, if he fulfills all the requirements, he can eventually become a US citizen if he wishes to do so, but it is not automatic.
