How long can a foreigner reside in Mexico?
When you arrive in Mexico, a tourist visa is issued with a maximum period of 6 months. They can be updated at the local migration offices. You also have the option to apply for a FM3, which has a 12 month period of validity. FM3s can be obtained if you are a property owner, if your employer is a Mexican Corporation, and in other special cases. Laws are constantly changing and you should call your local immigration office to make sure these laws are still in place.
