A Family Visa is a type of visa that allows family members of a person living in a foreign country to join them. This visa is often used by spouses, children, or other close relatives who wish to reunite with their family members who have legal residency or citizenship in that country. The application process for a Family Visa typically requires proof of the family relationship, such as marriage certificates or birth certificates. Each country has its own specific requirements and regulations, so it's important for applicants to check the guidelines provided by the relevant immigration authority.
