Holding two passports can make travel complicated. For dual citizens of Vietnam, the passport you present at immigration determines your entire legal status.
The Golden Rule: Your Passport Dictates Your Status
In Vietnam, your legal status is determined entirely by the passport you use to cross the border. You must use the **same passport** for both entry and exit.
Entering on a Vietnamese Passport
If you present your Vietnamese passport to immigration, you enter as a Vietnamese citizen.
- **No Visa Required:** You can enter freely and stay indefinitely without applying for a visa or exemption certificate.
- **No 2026 Pre-Arrival Form:** Vietnamese citizens entering on their national passport are exempt from the new digital pre-arrival declaration (effective April 2026).
- **Rights & Obligations:** You enjoy the rights of a citizen but are also subject to domestic laws (e.g., exit bans if you have outstanding tax debts in Vietnam).
Entering on a Foreign Passport
If you present your foreign passport (e.g., US, Australian, French), you enter as a foreign national, despite having Vietnamese blood.
- **Visa or Exemption Required:** You must apply for an eVisa, or hold a 5-Year Visa Exemption Certificate.
- **Pre-Arrival Declaration:** As of 2026, if you enter on a foreign passport, you **must** complete the online digital pre-arrival declaration before arriving at major airports like Tan Son Nhat.
- **Stay Limits:** You must adhere strictly to the expiration date stamped in your foreign passport. Overstaying will result in fines.
Never mix passports. If you enter on your US passport, you cannot show your Vietnamese passport when leaving to avoid an overstay fine. The immigration system tracks entries and exits by document number.
Frequently Asked Questions
Can I show my foreign passport to the airline and my Vietnamese passport to immigration?
Yes. This is the standard procedure. You show your foreign passport at check-in (so the airline knows you can return to that country) and your Vietnamese passport to the immigration officer upon landing in Vietnam.
Does Vietnam officially allow dual citizenship?
Vietnam generally recognizes only one nationality, but the Law on Nationality allows exceptions, especially for overseas Vietnamese (Viet Kieu) who retain their Vietnamese citizenship while naturalizing elsewhere.
