The tourism e-visa is a single entry visa issued to tourists from any of the 100 eligible countries. If your country makes a list and you wish to visit Azerbaijan for a short while, this e-visa is ideal. The tourist e-visa is valid for 90 days and allows you to stay in the country for 30 days. You can use it for vacation, attend sporting or social events, visit friends and family in Azerbaijan, or for humanitarian services. However, you must use the visa within 90 days after it is released so it doesn't expire. Also, note that the e-visa is linked to your passport, so you must travel with the passport you used for the application. If your passport will expire in the next six months, endeavor to apply for a new one before applying for the visa.
