How do China students with Russian study visa go through the formalities in Thailand?

Actually, your question is very simple. If you come to Thailand with a China passport, you don't need to apply for a visa in advance. You only need to apply for a visa when you arrive at the Thai airport. However, there are a few points that you must pay attention to. First, you must prepare a return air ticket with a fixed date, and the return date of the air ticket cannot exceed the date when you can stay in Thailand (the validity period of the visa on arrival with a China passport is 15 days). Second, sometimes the immigration department will ask you to show cash. According to the requirements of Thailand's immigration law, if you travel to Thailand, you must have no less than $500 in cash. You don't have to check this, but if you find that there is not enough cash, you are definitely not allowed to enter the country. So pay more attention. Third, you may be asked where you live in Thailand, and you must fill it in when you enter the country. Give you the name of a hotel, where China people live. Fourth, the visa fee on arrival is 1000 baht, so it can only be paid in Thai baht, so you can change it before you come, or after you arrive, but not too much. Change it in the city. The exchange rate is much better.
