Vietnam has launched a new e-Visa system, and it's the cheapest way to legally enter the country. On top of that, Korean Air has dropped San Francisco–Hanoi fares to $798 roundtrip including all taxes. Below is a practical breakdown: how to get an e-Visa, what it costs, and how to pay for your trip if your card doesn't work abroad.
The flight deal
This is the San Francisco–Hanoi route operated by Korean Air. The price is $798 roundtrip, all taxes and fees included. Sample travel date from the source: January 20–27, 2027. Keep in mind this is just one option — fares change fast and availability at this price isn't guaranteed.
Vietnam's e-Visa: what's changed
Vietnam has introduced a new electronic visa system. It's considered the cheapest way to obtain entry permission. Applications are submitted online through the official portal. The visa covers tourism and short-term stays.
The source doesn't provide exact processing times, the fee amount, or an official portal link, so check current requirements on Vietnam's immigration website before applying. Avoid third-party visa sites — they often add a markup.
The payment side of the trip
Paying the visa fee with a foreign card is a classic point of failure: Russian Visa and Mastercard don't work abroad, and some overseas services reject cards issued in certain jurisdictions. A virtual card solves this — you can issue one for a specific task, top it up with USDT, and pay the fee or hotel booking.
- Visa fee. Paid online on the official portal. If your card fails, check whether the payment system supports 3-D Secure and whether your bank blocks transactions in VND or USD.
- Hotel booking. Many hotels in Vietnam request pre-authorization — a temporary hold on your card. Virtual cards with limits may decline this. Ask the hotel in advance whether they accept debit cards and what deposit is required.
- Refunds. If a booking is cancelled, pre-authorization isn't released instantly — it can take days or weeks. Budget with a buffer.
- Currency. Vietnam uses the dong (VND). Cards with payment-system conversion are usually cheaper than airport exchange counters.
- eSIM and taxis. A local eSIM is easy to buy online before your trip — again, payment depends on your card. For taxis, Grab or local apps linked to a card come in handy.
What to check before buying the ticket
Make sure your passport is valid well beyond your trip and your e-Visa is issued before departure. If you're transiting through Seoul, check whether you need a South Korean transit visa — most nationalities don't for short layovers, but rules change.
