What is laissez-passer?

Laissez-passer is a French term that translates to 'let pass' or 'let go'. It is a document that acts as a travel permit allowing its holder to enter or leave a country. Laissez-passers are usually issued to individuals who have an urgent need to travel but don't have the proper travel documents, such as a passport or visa. They are usually issued by an embassy or consulate and are valid for a short period of time. The document may also be used to provide temporary protection or immunity to individuals who are engaged in certain official or diplomatic activities. However, a laissez-passer does not guarantee entry into a country and it is up to the immigration officials to determine whether or not to permit entry based on their policies and regulations.
