visa

A visa is an official authorization that allows a person to enter, stay, or leave a foreign country for a specified period and purpose. It is typically issued by the destination country's embassy or consulate and comes in various types, including tourist, work, student, business, and transit visas. The application process varies depending on the country and visa type and may require documents such as a copyright, proof of funds, travel itinerary, and sometimes a medical check or security clearance. Some visas are stamped on the copyright, while others are issued electronically. Certain countries offer visa-free entry or visa-on-arrival options for specific nationalities. A valid visa ensures legal entry and compliance with immigration laws.
