Family reunification visas are special permits that allow family members to join their relatives who are living in another country. These visas are designed to help maintain family unity by enabling spouses, children, and sometimes other relatives to live together. Each country has its own rules and requirements for these visas, which can include proof of relationship and financial stability. The process for obtaining a family reunification visa typically involves submitting an application to the relevant government agency, such as the U.S. Citizenship and Immigration Services in the United States. Approval can take time, and applicants may need to provide various documents, including identification and evidence of their family relationship.
