How long after my 30 day visa can I use my 15 day exemption?

Dear Sir/Madam,

Thanks for your question.

We would like to confirm that if you want to get 15 days Visa exemption, the gap between your entries must be 30 days at least.

So, you need Visa to enter Vietnam for the second time from Thailand.

You can apply for Visa here visavietnam.ws/evisa/administrator/visa_booking.html. We will process your Visa within 2 working days.

Please feel free to contact us if you have any question.

Thanks,

EVisa Team
