Consular services for U.S. citizens

The American Citizen Services unit in Hanoi handles:

New and renewed U.S. passports, replacement of lost or stolen passports, including emergency passports for urgent travel.
Consular Reports of Birth Abroad (CRBA) and first passports for children born in Vietnam.
Notarial services: acknowledging signatures on powers of attorney, affidavits and documents for use in the United States.
Emergency help: finding medical care, explaining how to report a crime, contacting family with your consent, following up on arrests, lists of attorneys and emergency repatriation loans.

Note: the Embassy cannot authenticate U.S.-issued documents while you are in Vietnam – they must be processed in the United States (see the apostille section below).

Before you go

Go to the right building: citizen services are at the Consular Section, 170 Ngoc Khanh, not the chancery at 7 Lang Ha.
An appointment is required. Walk-ins are usually told to call or email for a slot. ACS appointments can be booked out for weeks; for genuine emergencies (urgent travel, illness) request an earlier slot through the ACS inquiry form.
Visitors often report that the phone line goes to an automated system, while emails are answered fairly quickly – use email or the form and state your travel date.
For a child’s passport where one parent cannot attend, bring the notarised consent form required by the State Department and confirm in advance that your documents will be accepted.
Expect airport-style security screening; keep bags and electronics to a minimum.
Closed on Vietnamese and U.S. public holidays.

Why foreigners usually contact the Embassy

Lost or stolen passport. Report it to the local police to get a confirmation, then request an urgent ACS appointment for a replacement. Your Vietnamese visa was in the old passport, so once you have the new one you must obtain a new visa or complete exit procedures with Vietnam Immigration before flying.

Passport about to expire. Renew at the Embassy; if you hold a long-term visa or temporary residence card, it must be transferred to the new passport. U.S. citizens are not visa-exempt in Vietnam, so most use the Vietnam e-visa (up to 90 days) or a sponsored visa extension.

Marriage, births and work permits. Americans marrying in Vietnam usually need a sworn statement of marital status with a signature notarised by the Embassy; those taking a job need apostilled degrees and an FBI background check plus a notarised translation. Children born in Vietnam need a CRBA and passport, followed by a visa or residence card.

Voting. U.S. citizens abroad register and request absentee ballots through FVAP; ACS can notarise related documents if needed.

Getting a U.S. passport while in Vietnam

The Consular Section in Hanoi accepts new and renewal passport applications by appointment booked through USTravelDocs. Applicants – especially children and first-time applicants – normally attend in person, with both parents present or a consent form.

Info Travel helps within what the Embassy permits: booking guidance, form checks, compliant photos, translations of Vietnamese birth or marriage certificates and directions to 170 Ngoc Khanh. Once you receive the new passport, we transfer your visa or residence card, obtain a new visa or arrange exit procedures. We do not attend interviews or biometrics on your behalf.

Consular legalisation, MOFA/DOFA certification and notarised translation

The United States has been a party to the Apostille Convention since 1981 and did not object to Vietnam’s accession (31 December 2025). From 11 September 2026, documents between the two countries use an apostille; consular legalisation is only a fallback. See: apostille vs consular legalisation.

a) U.S. documents for use in Vietnam: state-issued documents (birth and marriage certificates, notarised degrees) are apostilled by that state’s Secretary of State; federal documents (such as an FBI background check) by the U.S. Department of State Office of Authentications. Then obtain a notarised translation into Vietnamese. If an office still insists on the old route: authentication in the U.S. and legalisation at a Vietnamese embassy or consulate there – unless an international treaty exempts the document. Signatures notarised by ACS in Hanoi may need consular certification by the Consular Department when used in Vietnam, depending on the receiving office.

b) Vietnamese documents for use in the U.S.: obtain an apostille from the Consular Department (MOFA, Hanoi) or the Ho Chi Minh City Department of Foreign Affairs, with an English translation.

Info Travel handles the full chain – translation, notarisation, filing and collecting the apostille or certification at MOFA/DOFA. See our consular legalisation service; quotes on WhatsApp +84327828822.
