When you enter Vietnam, you have to submit The Entry and exit form to the Immigration Officer. It is an important document as approval letter to get visa stamp. Since March 1, 2015, a new one that was renamed into Vietnamese visa application form has replaced the old entry and exit form. As such, the old form is currently invalid. Therefore, in case you received the old form for getting Vietnam visa on arrival at the airport from any travel agent, please ignore it, download the new version, fill it out and bring it together with you upon departure for Vietnam.
In case you do not have the Vietnamese visa application form from any source yet, you can take one at the airport upon your arrival to fill out with your information. However, it may take you 5 to 10 minutes to fill out. So we highly recommend you to download and fill it out before visit Vietnam to save your time. » Click here to download it.
