Multiple entry

Dear Khandaker Erfan

It is informed that we can help you to process 1 month single tourist visa for you and the service fee is $150US/person (not including $25US stamping fee at Vietnam airport). However, the Vietnam Immigration does not process 1 month visa for full 30 days, they just base on your ticket to process visa. The processing will take 7 working days
And you can apply for a Visa on arrival online at this link: https://www.vietnam-evisa.org/apply-visa.html
In addition, after finishing payment online, please send us your passport scan + hotel booking + return ticket + The first page of your credit card which you use to pay to us via email visa@vietnam-evisa.org. Without those documents, we cannot process a visa for you.

Regards, 

Amanda - Evisa team
