entry on ground from cambodia

Dear Sir/ Madam

Thank you for your question.

We would like to inform that you cannot use the visa approval letter to get a visa stamp at the border by road. Because this letter is only valid at Vietnam airport and you have to enter Vietnam by plane. In case, you will travel to Vietnam by road, please contact to Vietnam Embassy in your living country or in Cambodia to get your visa before coming to Vietnam.

Any more questions, please feel free to contact us.

Best Regards,

Susan (Ms.)
