I'm from another province. I want to go to Vietnam from the mouth of Yunnan and spend a day in the old street.

You need a visa, but if you just want to stay for one day, you can go to the travel agency in Hekou County and ask them to apply for a pass for you. They can do it quickly. 1. A visa is the endorsement and seal of a country, and it is a passport or other travel document held by the U.S. sovereign authority for its own or foreign citizens to show that they are allowed to enter or leave the U.S. territory or pass through the country's territory. It can also be said that it is an endorsement certificate issued to them. Generally speaking, a visa is a document issued by a country, and the entry and exit administration department of the United States (such as the Immigration Bureau or its embassies and consulates abroad) approves the entry of foreign citizens. 3. Passport is the holder's proof of American nationality and identity, while visa is the permission of sovereign countries to allow foreign or domestic citizens to enter, exit or pass. 4. Visas are generally endorsed on passports, some are endorsed on other travel documents instead of passports, and some are issued separately. For example, immigration visas in the United States and Canada are A4 paper, and Singapore also issues separate visas to foreigners. Generally speaking, a visa must be used with a passport to be valid.

What's the procedure for going to Vietnam?

Citizens who apply for private passports only need to bring their ID cards, original household registration books and photocopies to the local police station! Residents of municipalities directly under the central government shall handle it at the Municipal Exit-Entry Administration Center. (For example, Beijing hukou residents can apply at the Beijing Exit-Entry Administration Center, Luohu District residents of Shenzhen Special Economic Zone can apply at the Exit-Entry Administration Center of the Municipal Public Security Bureau, and Futian District residents can apply at the nearest Futian Branch of Shenzhen). It's best to call the local exit-entry administration center in advance and ask where I can apply for residence. The processing time is about 3 working days in Beijing, 3-5 working days in Shanghai, 7- 15 working days in other municipalities and provincial capitals, 0/0-20 working days in prefecture-level cities and 25 working days in county towns! Apply within one month at the latest! General expenses 200 yuan. If you need express delivery, you need 250 yuan! Generally, 250 yuan will not apply for a Vietnamese visa in the future. All you need is the original passport and a photo! The cost is about 500 yuan RMB!
