Business visa Vietnam is issued to foreigners who enter the country to work with businesses in the country which is valid up to a year.
You should clarify about the time that visa Vietnam is valid for before applying in order not to pay a more extra fee. The time between visa issuance and expiration date (shown on the visa along with the visa issuance date) is called your validity of visa Vietnam. The visa validity is the length of time you are permitted to travel to a port-of-entry in Vietnam.
The two photos handed to Vietnam Immigration Department once you arrive at the airports are very necessary, compulsory and should be taken in right format. Because of the ignorance about the photo’s requirement, some are obliged to take other photos at the airport with the cost of 2-5$/person and that waste a lot of time to get the Vietnam visa on arrival done.
E visa Vietnam allows you to travel to the country in three different ways and travelling by boat is one of the most interests that you should try. There is no exaggeration to tell that this is a start of a adventureful vacation.
