The Work Permit in Mexico is intended for foreigners who already have temporary residence and want to carry out work activities within the country. This permit allows temporary residents to legally work in Mexico for a registered or self-employed company. To obtain it, temporary resident aliens must request the change or addition of their immigration status to the National Institute of Migration (INM). The applicant must have a formal job offer or demonstrate independent economic activities. The procedure can be carried out while you are already in Mexico and you do not need to leave the country. It is a fundamental step to regularize employment status within Mexican territory.
