A-1 Visa: Who Qualifies, How to Apply, and Immunity

The A-1 visa is the U.S. nonimmigrant classification for ambassadors, career diplomatic and consular officers, heads of state and government, and other senior foreign officials traveling to the United States on official business, together with their immediate family members. Federal law defines this group in 8 U.S.C. § 1101(a)(15)(A)(i) as accredited representatives of foreign governments the United States recognizes.¹ The classification comes with fee waivers, interview exemptions, and broad diplomatic immunity, but it is reserved for the most senior tier of a foreign government’s personnel.

Who Qualifies

The A-1 category is narrower than most people expect. Under the Immigration and Nationality Act, it applies specifically to ambassadors, public ministers, and career diplomatic or consular officers accredited by a foreign government the United States recognizes.¹ Heads of state and heads of government qualify for A-1 status regardless of the purpose of their trip, so even a personal vacation still calls for the classification.²

The Department of State lists several groups within the A-1 tier:

Ambassadors and career consular officers serving at a foreign embassy or consulate in the United States
Cabinet-level ministers at a rank equivalent to a U.S. cabinet secretary, traveling on official duties for no more than 90 days
Principal representatives of European Union and African Union delegations
The spouse and qualifying children of any A-1 principal

Regardless of rank, the official must be accredited by a recognized foreign government, intend to engage solely in official activities while in the country, and be accepted by the President, the Secretary of State, or a consular officer acting on the Secretary’s behalf.⁴ Government officials traveling for commercial purposes or tourism do not qualify for an A visa even when their government has an ownership interest in the activity involved.³

How A-1 Differs From A-2

The A-2 visa covers the rest of a foreign government’s official delegation: rank-and-file employees assigned to an embassy, officials representing their government for under 90 days on written request, staff of EU and AU delegations, and foreign military members stationed at U.S. bases or embassies.³ The practical difference matters. A-1 holders receive the highest level of diplomatic immunity; A-2 holders often receive more limited protections.

How to Apply

The Diplomatic Note

The sending government submits a diplomatic note to the U.S. Department of State before the visa can be issued. It must include the official’s full name, date of birth, position and title, place of assignment, purpose of travel, a brief description of duties, travel dates, and the anticipated length of stay, along with the names, relationships, and dates of birth of any dependents or household members traveling with the official.⁵ Routine renewals of an existing A-1 visa inside the United States generally do not require a new diplomatic note.

Forms

First-time applicants applying from outside the United States complete Form DS-160, the standard online nonimmigrant visa application. Applicants who already hold an A-1 or A-2 visa and are reapplying while on assignment inside the United States use Form DS-1648 instead.³ A valid passport is required, and digital photographs meeting the Department of State’s specifications are uploaded with the application.

Fee and Interview Waivers

Applicants who qualify for an official visa classification, including A visas, are exempt from paying the visa application fee.³ They are also generally exempt from the in-person consular interview most nonimmigrant applicants must attend. As of September 2025, the Department of State lists A-1 applicants among the categories that do not require an interview.⁶ A police certificate is not required either, even if a consular officer suspects a criminal record exists.⁷

The application package typically moves through the sending government’s Ministry of Foreign Affairs or protocol office, which coordinates directly with the U.S. Embassy or Consulate, bypassing the public appointment systems used for tourist or business visas. Once approved, the visa is placed in the diplomatic passport, and the official presents it at a U.S. port of entry, where Customs and Border Protection acknowledges the diplomatic standing.

Immediate Family

The A-1 classification extends to members of the principal’s immediate family. Under 22 CFR 41.22, a qualifying family member receives the same A-1 classification as the principal.⁴ Those family members must be listed in the original diplomatic note so their status is processed alongside the principal’s application.⁵

For employment purposes, federal regulations define a “dependent” of an A-1 principal as an immediate family member habitually residing in the same household: the spouse, unmarried children under 21, unmarried sons or daughters under 23 who are full-time students at a post-secondary institution, and, under certain older bilateral agreements, unmarried sons or daughters under 25 who are full-time students.⁸ Family members’ legal status is tied to the principal’s continued eligibility. If the principal’s mission ends, the family members’ authorization to remain ends with it.

Work Authorization for Dependents

Dependents are not automatically authorized to work. They may become eligible through the Department of State’s Dependent Work Authorization Program. The United States has bilateral work agreements with over 100 countries and informal arrangements with more than 30 others. Under these agreements, certain dependents of A, G, and NATO visa holders can obtain authorization to work in the U.S. economy, provided the foreign state offers the same opportunity to U.S. diplomatic families posted there.⁹ Applications go through the Office of Foreign Missions, and authorization depends on whether a qualifying agreement exists with the sending country.

Diplomatic Immunity

This is the A-1 visa’s most consequential privilege. Diplomatic agents accredited to the United States have full immunity from criminal prosecution under Article 31 of the Vienna Convention on Diplomatic Relations. They also have immunity from civil and administrative lawsuits, with three narrow exceptions: disputes over private real estate in the United States, inheritance matters in which the diplomat is involved as a private person, and lawsuits related to commercial activity the diplomat conducts outside official functions.¹⁰ A diplomatic agent cannot be compelled to testify as a witness, and no enforcement action can be taken against them except in those limited scenarios.

Immunity is not as absolute as commonly assumed. Department of State guidance to law enforcement stresses that different classes of mission personnel receive different levels of protection, and the specific level depends on the individual’s accredited status rather than the visa stamp in their passport. Holding a diplomatic passport or an A-1 visa is not by itself conclusive proof of immunity; that determination comes from official accreditation records maintained by the Department of State.¹¹

Immunity also belongs to the sending state, not the individual. The sending government can waive it at any time, exposing the official to the jurisdiction of U.S. courts. And it does not last forever. Once the assignment ends, protection terminates after a reasonable period allowed for departure.¹¹

Tax Exemption Cards

A-1 holders can apply for tax exemption cards issued by the Department of State’s Office of Foreign Missions. Mission tax exemption cards are available to principal members or employees of the mission who hold an A-series visa and are not considered permanently resident in the United States. Personal tax exemption cards are available on a case-by-case basis to individuals accredited as diplomatic agents, administrative and technical staff, consular officers, and consular employees, along with their household family members.¹²

These cards provide point-of-sale exemption from sales taxes and similar taxes on most purchases of goods and services, hotel stays, and restaurant meals throughout the United States. They do not cover motor vehicle purchases, gasoline and diesel fuel, utility services, airline tickets, or cruises. Applications are submitted through the Department’s E-Government system and are generally processed within five business days.¹²

When the Assignment Ends

A-1 status is tied to the official assignment. When the mission concludes, the official and their family members must depart within a reasonable period, and diplomatic immunity terminates at that point. Anyone who wants to stay in a different capacity must change their nonimmigrant status or adjust to lawful permanent resident status before the diplomatic assignment formally ends.

The mechanism is Form I-566, submitted through the applicant’s diplomatic mission or international organization to USCIS.¹³ Under INA § 247, a lawful permanent resident who takes on a diplomatic role can keep their green card by filing a written waiver of all diplomatic rights, privileges, and immunities that would otherwise come with the A-1 classification, and the same provision works in reverse: a diplomat seeking permanent residence must formally relinquish diplomatic protections before adjusting status. Skipping these steps before the assignment ends leaves the individual without lawful status and without the shield of immunity, a combination that can lead to removal proceedings and future inadmissibility.
