Multiple entry visa

Dear Suchandra Dutta Roy,

Thank you for your question.

In your case, you should apply multiple entries visa to enter many times to Vietnam.

If you agree, you can do it here: : http://www.vietnam-evisa.org/apply-visa.html. After receiving your payment, we will process and send to you the approval letter via your email, then just need print the letter out and use it to get visa stamp directly at Vietnam airport.

Regards,

Hari Nguyen (Ms.)
