Immigration law in Mexico

Immigration law in Mexico is based mainly on the Constitution, the Ley de Migración, and related administrative rules. It applies to visitors, temporary residents, permanent residents, and other foreign nationals. Entry and residence are different questions. A person may be allowed to enter Mexico for one purpose but still need a different document or permission to live, study, or work there. Common immigration categories include visitor status, temporary residence, and permanent residence. The category should match the real purpose of the stay, such as tourism, family life, study, employment, investment, or other lawful activity. The Instituto Nacional de Migración, commonly called the INM, handles many procedures inside Mexico. Mexican consulates also play an important role when a visa or consular step is required before travel. Work permission may depend on the person’s immigration status and on the employer or activity. A foreign national should not assume that entry as a visitor automatically permits paid work. Applications can involve identity documents, proof of the reason for the application, family or financial information, and forms issued by the relevant authority. Requirements can differ by nationality and by the procedure used. Residents usually need to keep their immigration card and personal information accurate. Changes involving address, employer, family circumstances, or travel documents may require an update with the INM. Mexico also has procedures for family unity, humanitarian situations, asylum, and recognition of refugee status. These routes are different from ordinary visitor or residence applications and may involve specialized authorities.
