An Immigration Visa is a legal document that allows a person to enter, stay, and work in a foreign country. It is typically required for individuals who wish to move permanently or for an extended period. Different types of visas exist, such as family-sponsored, employment-based, and student visas, each with specific eligibility criteria and application processes. To obtain an immigration visa, applicants usually need to provide documentation, such as proof of identity, financial stability, and sometimes a job offer or family relationship in the host country. The process can vary significantly depending on the country's immigration laws and policies, such as those of the United States or Canada.
