How to switch visa

Dear sir/ madam, 

Thanks for your question,

We would like to inform that You are also allowed enter VN through tourist visa and admission in any course in a Vietnamese university. Then you apply a student visa.

Please kindly go to the Immigration Department to apply for a student visa or you can thank to your school to support for this case. 

Thanks and best regrads,
