What are the visa & residency requirements in Monterrey?

"In order to stay in Monterrey, foreigners must obtain a visa depending on the length of their stay. There are a variety of visa types available, including tourist visas, student visas, transit visas and permanent resident visas. To apply for a visa, applicants must provide their personal information, proof of identity, proof of financial capacity and, in some cases, proof of educational attainment. In order to obtain residency in Monterrey, applicants must submit an application to the nearest immigration office. This application will require proof of identity and financial capacity, as well as residence in Monterrey. Applicants can also be required to provide a criminal record and medical history. Once the application is accepted, the applicant will receive a registration sticker to be affixed to their passport. This is typically valid for up to 6 months, after which the applicant must renew it. Additionally, applicants must submit proof of having met certain residence requirements, such as having stayed for a certain amount of time each year in Mexico," explained one expat living in Monterrey, Mexico.
