Do international travelers need proof of an onward ticket when flying to Vietnam?

In late August, a traveler used Sheremetyevo’s automated border gates for both departure and return and was not asked about travel plans or tickets.

A couple departing through Sheremetyevo on 25 August said border officers asked neither for return tickets nor to inspect their phones.

For a Vietnam flight, it is safer to have proof of any onward departure rather than specifically a return ticket: airline staff may request it at check-in or boarding.

Passengers flying to Hanoi in late August with an e-visa reported no questions about return tickets at Russian departure control or Vietnamese immigration, with quick processing in Hanoi.

During transit in China, travelers reported a detailed inspection of bags and electronics. A power bank was accepted after its 3C certification marking was shown.
