Arranging your travel to Bhutan is not difficult as you assume. Once you get in touch with any of the local tour operators, you will be advised to produce documents necessary to process your visas and your travel can be arranged within few days including your visas, Drukair flights, hotels, guides, transport and other logistics.
Indian, Bangladeshis and Maldivian nationals can obtain a visa at the port of entry on producing a valid passport with a minimum of 6 month validity (Indian nationals may also use their Voters Identity Card (VIC)).
Bhutan visas should be arranged through any of the tour operators in Bhutan (all the tour operators in Bhutan are registered by the government of Bhutan). No foreign missions or embassies abroad sanction tourist's visas. As per the government regulations, you are required to make full tour payment in advance and upon receipt of full payment, your tour operators will process visas with the government. It normally takes 2-3 working days to clear your visas. The Bhutan visa confirmation letter will be sent to you in advance and your actual Bhutan visas will be stamped in your passports on the strength of this confirmation letter on arrival at Paro airport. You will have to carry this copy along with you always. Some airports do not allow you to board Drukair flights if you do not have this copy.
For the visa application process, you will have to send scanned copies of your passport. Visa fee US $ 40 per person is payable extra and it can paid along with tour payment.
In order to streamline and facilitate smooth visitation by tourists from Bangladesh, India and Maldives, the Department of Immigration, Ministry of Home and Cultural Affairs and the Tourism Council of Bhutan have launched the Online Permit System. The system facilitates the online processing of permits for regional tourists through registered Bhutanese tour operators and TCB certified hotels. The facility is offered as an optional channel to process permits for visitors from the region and is applicable for entry from Paro and Phuntsholing. Visitors who use this facility will be able to obtain their permit clearances and route permits ahead of their arrival in Bhutan similar to international tourists.
