Do I need a health certificate to apply for a visa to Vietnam? What kind of visa does not require a health certificate?

Vietnam is one of the countries that need health certificates. No matter what kind of visa, you need to apply. If you apply in the Mainland, you can consult with the Exit-Entry Administration. If you go by land, you can go to the border port town. I have never checked my health certificate by plane. By the way, if you really don't want to apply for a permit, you can put 20-30 yuan RMB in your passport and give it to the Vietnamese Customs.
