Visa:
All foreigners, except Indians, must have a visa. Citizen of South Asian countries and China need visas but these are free of charge. Nepali embassies and consulates overseas issue visas without problems. It is also possible to get a visa on arrival when you arrive in Nepal, either at Kathmandu's Tribhuvan Airport or at road borders: Nepalganj, Birganj/Raxaul Bazaar, Sunauli, Kakarbhitta, Mahendranagar, Dhangadhi and even at the Kodari checkpoint on the road to Tibet.
A Nepali visa is valid for a single entry for three to six months from the date of issue. Children below 10 require a visa but are not charged a visa fee. The passport must have at least six months of validity.
To obtain a visa on arrival it is necessary to fill in an application form and provide a passport photograph. A single-entry visa valid for 60 days costs US$30.
At Nepali embassies abroad it is possible to get a multiple-entry visa (US$80 or equivalent), which gives you multiple trips into Nepal for a year, with each stay valid for 60 days, up to a total of 150 days in any calendar year.
Visa extensions:
Visa extensions are available from immigration offices in Kathmandu and Pokhara only and cost US$30 (payable in rupees) for a 30-day extension. Every visa extension requires the passport, money, photos and an application form. Visa extensions are available the same day, often within an hour. You can extend your visa up to a total stay of 120 days without undue formality.
Entering Nepal:
The capital Kathmandu is linked by both air and road. Flights link it with Delhi, Kolkata, Varanasi, and Mumbai in India, Dhaka in Bangladesh, Karachi (Pakistan), Paro (Bhutan), Bangkok (Thailand), Singapore, Hongkong, Dubai, Frankfurt, London, Pairs, Osaka, and Lhasa.
The entry and exit points for foreigners entering into and departing from Nepal are listed below. The Immigration offices in such points are opened 24 hours. Entering and departing from other places except the point is treated as the violation of the law.
Permits
To trek in any part of Nepal, a trekking permit is required. The normal visa is only valid for the towns and the places reachable by road. All trekkers require a trekking permit to visit Nepal’s interior regions, which are not connected by highways. So if you want to trek two areas, you will need two permits and each permit requires details for the route and region. Police checkpoints are set up in some areas so do not venture off the set route because it will be really hard to find you in case you get lost. Recently the Annapurna, Langtang, and Everest regions have been declared "permit free"; the National Park or Conservation Area fees are still applicable.
