Transit rules depend on whether you pass border control and on your itinerary.
Transit requirements depend on your route and whether you need to pass border control (baggage, hotel, domestic connection). If you need entry, the e‑visa route is often the practical option; confirm using the official portals.
Fees vary
Fees depend on sub-route and can change. Confirm current official charges via the relevant Vietnamese government/consular channels before paying.
Vietnam Government News states e‑visa fees are US$25 (single entry) and US$50 (multiple entry). Fees may change and are non‑refundable if not granted; confirm before paying on official portals.
Use the official Vietnam Immigration Department e‑visa portals. The legacy portal posts a notice with the current domains: https://evisa.xuatnhapcanh.gov.vn/en_US/web/guest/home
