Understanding Vietnam’s Visa on Arrival system is essential for U.S. travelers because a missing approval letter, incorrect documents, or misunderstandings about VOA rules can easily lead to airport delays or even denial of entry. This guide provides everything Americans need—requirements, documents, procedures, and essential notes—to ensure a smooth arrival in Vietnam without unexpected complications.
Vietnam allows Visa on Arrival (VOA) for Americans, but it is not a walk-in service. U.S. citizens must have a pre-arranged visa approval letter issued by the Vietnam Immigration Department before boarding their flight. Without this document, the airline may refuse boarding, and the VOA counter in Vietnam will not process your visa.
VOA is available for several travel purposes, including tourism, business trips, and family visits, depending on your visa type. The system is convenient, but it requires preparation to ensure smooth entry.
If an American traveler arrives without the approval letter, immigration officers cannot grant a Visa on Arrival under any circumstance. The approval letter is the only document that authorizes airport-based processing.
VOA remains one of the most flexible options for Americans who prefer processing on arrival, but only when all prerequisites are completed correctly before departure.
U.S. citizens must hold a passport with at least six months of validity beyond their arrival date in Vietnam. This rule applies strictly, and any passport with shorter validity may result in denied boarding. Additionally, the passport must contain at least two blank pages to accommodate visa stickers and entry stamps.
A valid visa approval letter is mandatory. This official letter, issued by the Vietnam Immigration Department, confirms that the traveler is authorized to collect their visa upon arrival. It must be printed and presented at the VOA counter.
While not always required, having a return ticket or onward travel itinerary is recommended, especially for immigration checks. Hotel booking details or proof of accommodation may also be requested during inspection.
U.S. travelers must follow Vietnam’s entry and health regulations, including customs rules and any special requirements applicable during peak seasons or holidays.

Upon landing, Americans must provide a printed visa approval letter, which serves as the basis for VOA issuance. This document must match your passport details exactly. You must also submit the NA1 entry/exit form, preferably completed in advance to save processing time.
Two passport-size photos (4×6 cm) are required for the application. Bringing extra photos is recommended in case immigration officers request replacements. Your original U.S. passport is essential and will be held temporarily during visa processing at the airport.
The VOA stamping fee must be paid in cash. The fee is $25 USD for single-entry visas and $50 USD for multiple-entry visas. Credit cards and other currencies are often not accepted, so travelers should prepare the exact amount.
Travelers may also be asked for their hotel booking and itinerary, especially during busy seasons or if the approval letter indicates special processing notes.
Before your trip, apply for the visa approval letter through a licensed agent. Services like VietnamImmigration.com provide fast and reliable support. Once approved, print the letter, prepare your photos, and complete the NA1 form.
When you land at airports such as Noi Bai, Da Nang, Tan Son Nhat, Cam Ranh, Phu Quoc, Cat Bi, or Lien Khuong, head to the VOA counter before the immigration line. Submit your passport, approval letter, photos, and the NA1 form. Then pay the stamping fee in USD cash.
Processing usually takes 10–25 minutes depending on airport traffic. Immigration officers will verify your documents and print your visa sticker. Once completed, you will receive your passport with the visa attached.
After receiving your visa, proceed to the immigration lines to complete entry procedures and officially enter Vietnam.

The visa approval letter is a mandatory document that authorizes VOA issuance. It is provided by the Vietnam Immigration Department and cannot be skipped or replaced.
To obtain it, Americans must apply through an authorized agent such as VietnamImmigration.com, which handles submission, verification, and processing. This ensures your data is accurate and approved by immigration authorities.
Applicants must provide passport information, travel dates, entry airport, and the type of visa requested (tourist or business). The agent will review the information and submit it for approval.
Common mistakes include incorrect passport numbers, wrong arrival dates, or forgotten printing of the approval letter. Ensuring accuracy before submission prevents delays and rejections.
Standard approval letter processing takes 3–5 business days. This is the most common option for travelers planning ahead and is typically sufficient for most itineraries.
For urgent travel, expedited processing is available within 2–8 hours, depending on the service level. Same-day and 2-day processing options are also offered for time-sensitive trips.
Processing times may vary during Vietnamese public holidays, peak travel seasons, or if the submitted information is incomplete. Travelers should always consider these factors before scheduling their trip.
For the smoothest and safest experience, Americans are recommended to apply at least one week before their departure date.

Airport officers will inspect your passport carefully, so ensure it is undamaged and meets validity requirements. Any tears or missing pages may lead to refusal. Printed documents are strongly preferred; digital copies may not be accepted.
Avoid mistakes such as carrying expired photos, failing to print your approval letter, or not preparing exact stamping fees. These issues commonly cause delays for travelers arriving at high-traffic airports.
Vietnam’s health and customs regulations must also be followed. While most restrictions have been simplified, travelers should still be aware of current rules, especially during holiday periods.
To ensure a smooth entry, keep cash ready, prepare proper photos, complete forms before landing, and store all documents in an easily accessible folder.
Vietnam’s Visa on Arrival is a practical option for Americans, but it requires careful preparation. The approval letter is mandatory and must be obtained before flying. Travelers should print all documents, prepare photos, and bring the correct stamping fee to ensure a stress-free arrival. By applying through a trusted and experienced service like VietnamImmigration.com, U.S. citizens can enjoy fast processing, guaranteed approval, and complete peace of mind throughout their journey.
