You can open a visa to a country like Bangladesh in several ways:

Firstly, those arriving can put the necessary stamp in their passport with a mark directly at the airport in Dhaka, the capital of the country. However, in order to get a visa to Bangladesh in this way, you need to take care in advance and correctly collect the requested documents, get expert advice on the latest changes in the country’s visa policy, so as not to be taken by surprise after arrival.
Secondly, travelers can take care of issuing such permits as a visa to Bangladesh for Russians in advance and arrange them in their own country, the Russian Federation, by contacting the state embassy. As a rule, processing of documents such as a visa to Bangladesh takes about one week. If the issuance deadlines need to be prepared faster, the issue is resolved for an additional fee in the form of consular fees, the amount of which is approximately equal to the cost of the visa itself.

To issue permits for Russians with minor children, it will be necessary to issue national passports for them in advance and do not forget to take with you, just in case, their birth certificates.

Both options for obtaining a visa for Ukrainians, Belarusians, Kazakhstanis work in the same way, the price of obtaining a visa in a passport in both cases is also approximately equal and ranges from about fifty US dollars.

Kinds
