With the exception of travellers from a few neighbouring countries, all non-Vietnamese passport holders are required to have a valid visa to enter Vietnam. Visitors can obtain a tourist visa in one of three ways:

1) Do it yourself
In countries with a Vietnamese Embassy, prospective travellers to Vietnam can visit the Vietnam Embassy to collect an application form. Once the form has been completed and returned, the travel visa will be ready for collection about three working days later assuming there are no complications. In some countries, it is possible to have a visa sent by post, but the applicant will have to send his or her passport to the Embassy for validation.
The cost will be about $25 US or $30 US per visa, and the Embassy will levy a service charge on top. To find out how much the Embassy charges, and whether the Embassy will issue a visa by post, intending visitors should ring the Embassy and ask for the Visa section.

2) We deal with the paperwork
We send customers a form requesting basic information (names, dates, passport numbers and so on) by e-mail. When the completed from is returned, we apply to the Immigration Office in Hanoi. After about two (02) working days, we will receive an approval paper and fax it to the Vietnam Embassy in the customer's country. The customer can then send his or her passport by post to the embassy with a cheque for the visa fee, or collect it in person. It will be necessary to ring the Embassy to arrange a time for collection.
For this service, we charge $15US per person to cover our costs. The visa fee will be about $25 US or $30 US, making a total coat of $40 US to $45 US per person.

3) Visa on arrival
Customers without a Vietnamese Embassy in their country, those booking late, or those preferring to minimize paperwork, can ask us to process a 'visa on arrival'. This involves supplying us with a few details in advance and collecting your visa when you enter Vietnam.
We ask customers to supply us with the basic information needed to apply to the Immigration Office in Hanoi for a 'visa on arrival'. When the official approval document is issued, we send it to the customer as a fax, or scan it and send it by e-mail.
The process from our receipt of a customer's information and his or her receipt of the visa approval takes a maximum of two working days. Please note that the Immigration Office is closed at weekends, so you are pleased make request for Vietnam visa at weekend on those days.
For this service, we charge $15 US per person for the application procedure. The assistance at the airport which can be added to the cost of the visa if you wish. The customer has to pay a further $25 US for each visa directly to the Customs Department at the airport.
