To be accurate, you're talking about a 5 year multi entry visa exemption. You need to send to the consulate an application, a 2x2 photo, money order(you need to call to verify how much), and proof you or your immediate family are from Vietnam (like a birth certificate). I just renewed my visa exemption certificate through the San Francisco office. It cost me $70. I sent my paperwork monday and got the visa exemption certificate back that Saturday.
Hi, to get a certificate of singleness, you need to go to your local authority to get one. The cost will depend on the receiving agency
Hi, 5-year visa to Vietnam is issued at the embassy. All you need to do is submit your visa application and passport copy to the embassy
