Do you need to fill out a paper arrival card at Cam Ranh airport (Nha Trang, Vietnam)?

There appears to be no data sharing between agencies, so travelers on tourist visas are unlikely to be flagged for not filling out the card — unless there's suspicion of permanent residency. This is based on informal traveler experience, not official guidance.

Some travelers report having filled out a paper migration card and consider it mandatory. Whether it's strictly required at Cam Ranh specifically remains without a clear official answer.

Whether the electronic migration card replaces the paper one or both coexist is still unclear. No clear official stance specific to Cam Ranh has been confirmed by travelers.
