Visas are official documents issued by a country’s government that allow individuals to enter, stay, or work within that country for a specified period and purpose. Immigration, on the other hand, refers to the process of individuals moving to a foreign country with the intention of settling there permanently or semi-permanently.

Visa types vary depending on the purpose of travel and the duration of stay. Common types include tourist visas, work visas, student visas, and permanent residency visas. Each type has its own set of requirements and restrictions, which may include proof of financial stability, medical examinations, and background checks.

Immigration processes can be complex and are often governed by strict laws and regulations. Many countries have specific immigration programs and pathways designed to attract skilled workers, investors, or family members of citizens or permanent residents. These programs may have different eligibility criteria and application procedures.
