How Long Can US Citizens Stay in Vietnam
US citizens generally need a visa to enter Vietnam. The standard path is the official Vietnam e-visa, valid for a maximum of 90 days, available as single-entry (USD 25) or multiple-entry (USD 50) on the government portal. The US Embassy in Vietnam confirms e-visas are issued for up to 90 days at those fee levels. There is no broad US tourist visa exemption like Thailand's. Apply online before travel, match your entry port to an approved checkpoint, and leave on or before the e-visa end date.
This guide is for Americans planning Hanoi, Ho Chi Minh City, Da Nang, or multi-city Vietnam routes, including nomads who want a full 90-day stretch. The problem is outdated advice about visa exemption or 30-day tourist visas that no longer match the e-visa system most travelers use. You need current duration, fees, and application steps tied to official sources.

Do US citizens need a visa for Vietnam?
Yes for ordinary tourist and short business visits. US passport holders are not in the same unilateral short exemption category that some other nationalities may use for limited stays. The practical default is the national e-visa system open to foreign passport holders who meet eligibility rules on the portal.

Single vs multiple entry
| Option | Fee | Best for |
|---|---|---|
| Single entry | USD 25 | One continuous Vietnam stay up to 90 days |
| Multiple entry | USD 50 | Side trips to Cambodia/Laos/Thailand with return to Vietnam inside the e-visa validity |
Multiple entry does not create unlimited presence forever. It allows more than one entry during the e-visa validity window, still subject to the 90-day maximum framework of the e-visa product. Read your approval letter for exact valid-from and valid-to dates.
How to apply for a Vietnam e-visa
Step 1. Open the official portal at evisa.gov.vn. Avoid lookalike paid resellers unless you knowingly want a service agent.
Step 2. Prepare a passport valid for your stay (and any airline six-month rules), a digital photo meeting specifications, and your planned entry port.
Step 3. Complete the form carefully. Name and passport number must match the passport exactly.
Step 4. Pay the official fee (USD 25 or USD 50) through the portal's payment method.
Step 5. Wait for approval (often several business days; build buffer). Print or save the e-visa PDF.
Step 6. Enter only through an accepted international checkpoint listed for e-visa travelers, and carry the same passport used in the application.
Worked example with concrete dates
Avery, a US citizen, wants Vietnam from 15 September 2026 to 10 December 2026 (87 days). Avery applies on 20 August 2026 for a single-entry e-visa requesting the full period. Approval arrives 25 August 2026 with validity covering the stay.
Avery arrives in Hanoi on 15 September 2026 and must exit by the end date on the e-visa (not "90 days from whenever"). If Avery later wants a weekend in Bangkok on 1 November and a return to Ho Chi Minh City on 5 November, a multiple-entry e-visa would have been the correct product. On a single-entry visa, leaving Vietnam ends that entry.
Extensions, re-entry, and longer stays
E-visa rules and in-country extension options can change. Do not assume a tourist e-visa extends as easily as some neighboring countries' exemptions. If you need more than 90 days, plan a new lawful visa strategy or a different status rather than overstaying.
Leaving for Cambodia and returning only works if your visa allows another entry and remains valid. For general hop mechanics and risk, see how visa runs work.
Passport validity for multi-country Asia routes often follows the stricter six-month passport rule at airline check-in.
Remote work and purpose of stay
Tourist e-visas are for temporary visits consistent with the declared purpose. Local employment needs proper work authorization. Remote work for a foreign employer while traveling is common among nomads and still distinct from Vietnamese employment status. See remote work tourist visa legality and, for structured long stays elsewhere, what is a digital nomad visa.
Common mistakes
Using unofficial clone websites. Pay and apply on evisa.gov.vn when possible.
Typos in passport data. Small errors cause airport refusals.
Wrong entry airport vs approval. Match the checkpoint rules.
Assuming US citizens are visa-exempt. Plan the e-visa timeline.
Overstaying by a few days. Fines and future issues apply.

Frequently Asked Questions
How long can US citizens stay in Vietnam?
With a Vietnam e-visa, US citizens can stay up to 90 days, depending on the dates approved on the e-visa. The official portal offers single-entry and multiple-entry options at USD 25 and USD 50. Ordinary US tourists generally must obtain a visa in advance rather than relying on visa-free entry. Always follow the end date printed on your approval, not a generic "90 days from landing" assumption if the letter states fixed dates.
Do Americans need a visa for Vietnam in 2026?
Yes for typical tourism and short visits. The standard method is the official e-visa at evisa.gov.vn. The US Embassy in Vietnam describes e-visas valid up to 90 days for one or multiple entries at the official fee levels. Apply early enough to receive approval before your flight, and carry the approval with your passport. Do not rely on airport visa-on-arrival folklore that may not match current US passport procedures.
How much does a Vietnam e-visa cost for US citizens?
On the official national portal, the stated fees are USD 25 for a single-entry e-visa and USD 50 for a multiple-entry e-visa. Third-party agencies may charge extra service fees on top of the government fee. For most travelers, applying directly on the government site is enough if you can complete the form accurately. Budget extra time for payment confirmation and PDF download before you go to the airport.
Can I enter Vietnam twice on one e-visa?
Only if you obtained a multiple-entry e-visa and both entries fall within the validity period. A single-entry e-visa allows one entry only. If you plan side trips to neighboring countries with a return to Vietnam, choose multiple entry when you apply. Re-read your approval letter for exact conditions. Enter only through checkpoints that accept e-visas so you are not turned away at the border.
What happens if I overstay a Vietnam e-visa?
Overstaying can lead to fines, exit delays, and problems obtaining future Vietnamese visas. Exit on or before the authorized date. If an emergency prevents timely departure, contact Vietnamese immigration authorities for guidance rather than ignoring the expiry. Keep digital and printed copies of your e-visa for exit formalities. Set calendar alerts several days before the end date so you can change flights if needed.
