Overview of Vietnam Business Visa for U.S. Citizens

Vietnam’s economic ties with the United States have grown stronger in recent years, making the Business Visa (DN/DT categories) increasingly important for American travelers engaged in meetings, sourcing, negotiations, and commercial ventures. Unlike tourist visas, the business visa authorizes professional activities without requiring a full-time work permit.

It’s essential to distinguish between a Business Visa and a Work Visa. A Business Visa is for short-term, non-labor employment purposes—think site inspections, contract signings, or seminars. A Work Visa, on the other hand, applies when a U.S. citizen is hired by a Vietnamese entity for long-term employment and involves securing a Work Permit before entry.

Business Visas are commonly issued for 30 to 90 days and may allow for single or multiple entries. Some applicants may even qualify for six-month or 12-month multi-entry visas if the host company in Vietnam meets certain conditions.

Understanding the correct visa type ensures legal compliance and avoids future headaches with immigration.

Latest Updates on Vietnam Visa for Americans in 2025

As of 2025, the Vietnamese government has streamlined visa processing for foreign nationals, including U.S. citizens, in a bid to boost business travel and international cooperation. Several key improvements are now in place.

Firstly, embassy and consulate visa processing times are more efficient, typically ranging from 5 to 10 business days. Consular offices in major U.S. cities such as Washington D.C., San Francisco, and Houston are now better equipped to handle increased demand with clearer instructions and faster verification.

Secondly, the e-Visa system has expanded significantly, now covering multiple entry points, extended stays, and broader use cases—including short-term business visits. U.S. travelers can now apply for single-entry or multiple-entry e-Visas valid for up to 90 days, a major upgrade compared to past limitations.

Lastly, approval letter processing for Visa on Arrival (VOA) has also been optimized. Agencies and sponsors in Vietnam can now secure approval letters for foreign business travelers within just 3–5 working days, helping travelers cut through red tape while ensuring legitimacy.

Requirements & Documents for U.S. Applicants

To secure a Vietnam Business Visa, American applicants must prepare a precise and complete set of documentation. Missing or incorrect information can delay or deny visa issuance, so accuracy is key.

Core Requirements:

• Valid U.S. passport with at least six months remaining from the intended date of entry and two blank pages.
• Digital passport photo (standard 4×6 cm or 5×5 cm) on a white background.
• Visa application form, which varies slightly depending on the method of application (Form NA1 for in-person, e-Visa forms for online applications).
• Invitation letter issued by a legally registered business entity in Vietnam, confirming your business relationship and purpose of visit.
• Company documents from your Vietnamese host, such as their business license or tax registration.

Optional but Advantageous:

• Flight itinerary and hotel bookings, which can demonstrate intent and travel clarity.
• Proof of previous Vietnam travel history or business correspondence.
• Conference registration if attending a seminar or trade event.

Common Mistakes to Avoid:

• Submitting an invitation letter without proper stamps or government registration.
• Using a passport with less than six months’ validity.
• Providing unclear or incorrectly sized photos.
• Leaving key sections of the form blank or mismatched with supporting documents.

Providing additional supporting documentation, even if not mandatory, significantly increases the success rate and speeds up processing.

Application Methods – 3 Popular Options

There are three main channels through which U.S. citizens can apply for a Vietnam Business Visa, each with unique advantages depending on your timeline, access, and travel purpose.

1. Embassy/Consulate Application in the U.S.

This traditional method involves submitting all required documents directly to a Vietnamese embassy or consulate. It is considered highly reliable and suitable for those who want to secure their visa before traveling.

Processing time: 5–10 business days
Pros: Full visa in passport before departure; ideal for multi-entry and long-term visas
Cons: Requires mailing or visiting in person; limited flexibility for last-minute plans

2. Visa on Arrival (VOA) with Approval Letter

VOA is a common method for business travelers arriving by air. After obtaining an invitation and approval letter from a Vietnamese host company (processed through the Vietnam Immigration Department), the traveler receives their visa at a designated international airport.

Processing time for approval letter: 3–5 working days
Visa stamping time at airport: Around 30 minutes
Pros: No embassy visit required; suitable for urgent travel
Cons: Only valid for airport arrivals; not applicable to land or sea entries

3. E-Visa Online (Now Expanded for Business Use)

Vietnam’s e-Visa system now supports both tourism and short-term business visits, making it an excellent option for tech-savvy travelers.

You can apply entirely online and receive a PDF visa document via email—no embassy contact or arrival line needed.

Processing time: 3–5 business days
Validity: Up to 90 days, single or multiple entries depending on application
Pros: Simple, fast, digital; entry via airports, seaports, and land borders
Cons: Limited eligibility for complex business purposes; not suitable for long-term contracts
