Can a tourist visa from China to Thailand be changed to a student visa?

Generally speaking, there is no so-called student visa, only a study visa.

A tourist visa cannot be changed to a study visa after going to Thailand.

If you want to apply for a study visa,

I. Handling in China

Second, the school that accepts your study will send you an invitation letter, and then apply for a study visa with the invitation letter.

Third, the visa processing time is not long, generally in 1-3 working days.

You can transfer other visas in Thailand, but I suggest that it is best not to do so. Because if the study visa is a non-study visa, the certification of graduation certificate will be more troublesome after returning to China, and it may not be certified (that is, it will not be recognized in China). (A study abroad diploma needs to be certified after returning to China. One of the conditions is that the visa must be a study abroad visa. )

To sum up, I sincerely suggest that you take time off to apply for a study visa in China, and don't lose too much because of trivial matters.
