Hanoi Airport Arrivals
Passengers on international flights should be given a two-part customs form to fill out before arrival. On entering the terminal, follow the signs to immigration. You'll need your passport with the visa along with the customs form for immigration. After passing through immigration, you can collect your bags. There's only one baggage carrousel for international arrivals, so there's no confusing where to get your bags. Once you retrieve your bags, you must stop at the customs counter and submit your passport and customs form there. They will keep the top white copy and return your passport along with the yellow copy to you. Be sure to keep the yellow copy with your passport. You will need to submit it on your departure.
