Do international visitors need to complete an arrival/immigration card when entering Vietnam on an e-visa?

If the card was not completed beforehand, it can be filled out while waiting in the passport-control line. One family reported that it took about 10 minutes in total.

Use a good-quality photo for the e-visa application: one application was returned for revision because of the photo quality and was approved after the image was replaced.

In Hanoi, an arrival card may also go unchecked for e-visa arrivals; the passport receives a stamp showing the e-visa validity date. Even so, a traveler completed the form while in the queue as a precaution.

After arriving in Nha Trang, passport control may not check an arrival card. It is still best to complete it in advance rather than rely on the practice of a particular officer.
