From the Mexican immigration laws:

- Those seeking Mexican citizenship must show a birth certificate, provide a bank statement showing economic independence, pass an exam (In English?), and prove they can provide for their own health care.

-Illegal entry into Mexico is equivalent to a felony, punishable by two years imprisonment; document fraud is subject to fine or imprisonment; evading deportation is a serious crime, and re-entry after deportation is punishable by TEN years imprisonment.

- The Mexican government will ban foreigners if they upset “the equilibrium of the national demographics.”
