A spouse visa, also known as a marriage visa, allows the spouse of a citizen or permanent resident to live and work in their partner’s country. The visa is typically granted based on proof of a genuine and subsisting marriage. Requirements vary by country but generally include documentation of the marriage, proof of financial stability, and sometimes language proficiency. The application process often involves interviews and background checks. Once granted, the visa usually allows the spouse to work and may lead to permanent residency or citizenship after a certain period, depending on the country’s laws.
