With nearly 8 millions of internation tourists to Vietnam in 2015, Vietnam tourism expects to receive more tourist arrivals in the coming years thanks to easier Vietnam visa arrangemens and exemption.
Vietnam is now offering visa exemption for some nationalities in Asia like South Korea, Japan, Malaysia, Singapore, Thailand and other European countries such as UK, France, Germany, Italia, Spain which has showed sharp increase in tourist's arrivals from these countries.
There are two ways to obtain Vietnam visa now. The first way to to visit any Vietnamese embassy in your countries and apply for visa. The second and most inexpensive way is to contact a local tour operator in Vietnam who is on behalf of you to apply for Vietnam visa in Vietnam. This is called "Vietnam visa on arrival" and Vietnam visa provider is highly recommended.
From from early next year (2017), Vietnam will allow to apply electronic visa for foreign visitors to Vietnam. This is just trial run and not sure how it is going like, but it expects to give tourists to Vietnam another option to obtain Vietnam visa by yourselves.
