To joining a tour to visit Bhutan, you need a visa. Especially, the application for a visa to going to Bhutan is very difficult because tourists are required to have a visa before departure, so you can not apply for a visa at the airport as in other countries.
Therefore, most visitors traveling to Bhutan must go through the travel agencies to apply for visa guaranty. It is best to buy a Bhutan package tour of travel agencies in Vietnam or Bhutan to avoid problems arising because of the regulations of the Bhutanese government.
Visitors traveling to this country are required to spend at least $200 (in low season: January, February, June, July, August, December), or $250 (in peak season: March, April, March, September, October, November) for a day stay here. And this is the total amount of money that is included in the cost of tour payment when you buy tour at travel companies in Vietnam or Bhutan.
This amount of payment to the travel company will be directly transfer to the account of Tourism Council of Bhutan, after full payment, almost 100%, you will have a visa to visit Bhutan.
To apply for a visa, within 3 to 4 weeks before the date of departure you will need to provide some information such as: name, passport number, date of issue, place of issue, expiry date, occupation, nationality, date of birth, place of birth, permanent address, a scanned of passport (it’s best your passport must be valid longer than 6 months) to travel companies.
The visa costs $40 and you will pay that amount at Paro (Bhutan) airport when you enter Bhutan.
