A travel visa is a legal document that the government issues to allow someone to enter and remain in a nation for a predetermined amount of time. This official document serves as proof that the individual is authorised to be in the nation and is not doing so unlawfully. It gives them the freedom to enter the nation, stay there for a short time, and then depart without running afoul of the law. A travel or visiting visa is essentially made to allow anyone who is not a citizen of a certain country to visit that country.
