Migrating permanently to the USA typically involves obtaining a green card, which grants lawful permanent residence. The main pathways include family sponsorship (if you have a U.S. citizen or permanent resident relative), employment-based visas (for skilled workers, professionals, or investors), and the Diversity Visa (DV) Lottery, which offers limited slots to applicants from underrepresented countries. Refugee or asylum status may also lead to permanent residency. Once you hold a green card, you can live and work indefinitely in the USA and later apply for U.S. citizenship after meeting residency requirements.
