1. Passport with a minimum of 6 months validity.
2. You must provide your actual signed passport, including one copy of the personal information page of your passport.
3. Photographs (4cm x 4cm) – two photos are required for each applicant.
4. Visa Application Form Hotel Confirmation, if you have reserved accommodation in Nepal and wish to apply for a tourist visa at an international airport or border post (if applicable).
