Most visitors to Nepal can obtain a Tourist Visa on Arrival at Tribhuvan International Airport (and other entry points). The process is quick and straightforward, although there may be short queues during peak travel season. If you prefer to avoid waiting, you can also apply for a visa in advance at a Nepalese diplomatic mission abroad before your trip. Immigration Nepal
