Prepare the day before
Keep your passport ready, make sure your phone has data, and have cash prepared for border fees. If your booking includes a Vietnam visa, send passport and selfie uploads before the trip so the documents are ready before departure.
Double-check the passport expiry date, make sure the passport has enough blank pages, and keep any previous entry or exit stamps visible and easy to find. If you are traveling with children, family members, or a group, keep the passports together in one place so nothing gets misplaced during pickup. Save the WhatsApp photos to your phone before leaving so you can open them quickly at the border without searching through messages. For Cambodia payments, carry small cash notes because several travelers were instructed to keep 4 x 50,000 VND ready for official stamp fees, plus separate cash for the Cambodia visa when applicable. For printed documents, prepare a few 20,000 VND notes if a page needs to be printed during the trip.
