Mexico is a popular country for retirees. For decades, North Americans have been living indefinitely in Mexico by returning to the border and recrossing with a new tourist permit every 6 months. Mexican immigration officials have caught on, and now limit the maximum time in the country to 6 months within any year. This is to encourage even partial residents to acquire proper documentation.
