Differentiate between VISA and Passports.

Passport:
A passport is an official government-issued travel document that certifies the identity and nationality of the holder. It typically contains personal information, a photograph, and a signature. Passports are essential for international travel as they serve as proof of citizenship and allow individuals to enter foreign countries. They do not grant the right to enter a specific country but serve as a means of identification and a prerequisite for obtaining entry visas.

Visa:
A visa is an endorsement or stamp placed by officials of a foreign country on a passport that grants the holder permission to enter or stay in that country for a specified period and purpose. Visas are country-specific and have various types, such as tourist visas, work visas, and student visas. They are obtained through the consular or embassy offices of the destination country before travel. Possessing a visa does not guarantee entry; it simply allows the traveler to present themselves at the border for immigration inspection.

In summary, a passport is a document that establishes identity and citizenship, while a visa is an authorization permitting entry into a specific country for a designated purpose and duration. Passports are generally required for international travel, and visas may be required depending on the destination and the traveler's purpose.
