Can I exit Vietnam later than the granted exit date in my visa approval letter?

The answer is no.  An earlier exit is allowed but a later exit. However, you wish to stay more 1 month than your visa’s validity, we highly recommend you to extend your current visa. If it has 1 or 2 days more, you need to prepare to pay for the fine (at least US$50)

For visa extension, please send your passport scan, visa stamp and visa sticker to our email visa@vietnamvisateam.com, we will check with the Immigration Department then inform you about service fee.
