Immigrant, Not Economically Active (FM2)
When you want to acquire permanent residency but DO NOT want to work in Mexico:
If you are of retirement age (50+), and
have at least US$1,000 or equivalent
income per month (
plus an additional US$500 per month for each dependant, e.g. spouse), then a Retiree FM2 visa will be the most straightforward route.
NB: There is no 'official' minimum income, by law, that you need to prove; however the sums mentioned above are a rule-of-thumb and commensurate with the levels of income most retirees are being asked to prove.
If you are not of a retirement age (below 50) and want to live but not work in Mexico, you will need to contact the Mexican Consulate.
Provided that you can prove a steady income, you may be granted a FM2 visa to live in Mexico and seek permanent residency.
You will need to state what you intend to do there, e.g. early retirement due to health, etc.
*Sums are subject to change. Contact your local Mexican Consulate for the latest policy on investor's visas.
