(UNITED STATES) The United States has imposed a full visa suspension on nationals of Iran across all immigrant and nonimmigrant categories, a move that now shapes who can attend the 2025 United Nations General Assembly in New York. The policy stems from a Presidential Proclamation signed on June 4, 2025, and effective June 9, 2025, at 12:01 a.m. EDT. It subjects every Iranian visa application—even those for official UN business—to strict security review with limited exceptions. The change means much of Iran’s UNGA delegation may be unable to travel unless they already hold qualifying visas or fit narrow exemption rules.
U.S. officials say national security considerations drive the action, with President Trump’s proclamation suspending entry for nationals of 19 countries, including Iran. Under the policy, new visas for Iranian nationals in common categories such as B (tourist/business), F and J (students and exchange visitors), and M (vocational students) are not being issued. The Department of State has underscored that exceptions will be rare and handled under the highest scrutiny.

There are important carve-outs for diplomatic and UN-related travel, though they are not automatic. Iranian officials seeking to attend the UNGA must apply for the appropriate visa type, typically A-1 or A-2 for diplomats and G-1 through G-4 or C-2 and C-3 for UN-related travel. These categories are formally exempt from the blanket suspension, but each case undergoes a rigorous interagency security review. Only those who held valid diplomatic or UN-related visas as of June 9, 2025 are clearly outside the new restrictions; for others, approvals are possible but far from guaranteed.
Policy scope and immediate effects
- All nonimmigrant and immigrant visas for Iranian nationals are suspended, except for narrow exemptions.
- Diplomatic and UN-related visas (
A
,G
,C-2
,C-3
) remain possible, but applications face heightened vetting and can be refused. - Family-based immigrant visas are limited to specific cases:
- Spouses and parents of U.S. citizens may still qualify, provided they supply strong proof of the relationship.
- Green card holders sponsoring relatives are not covered by this exception.
- Fiancé(e) visas (
K-1
) are not exempt and will be denied. - Case-by-case waivers may be granted for U.S. national interest, humanitarian grounds, or criminal proceedings, but they are rare.
- No retroactive revocation: visas issued before June 9, 2025 remain valid.
- Dual nationals traveling on a passport from a non-suspended country are not subject to the ban.
For Iran’s UNGA delegation, the practical outcome is stark. Senior officials with existing valid diplomatic or UN visas should be able to travel, subject to security checks. Others—including many support staff, security personnel, and accompanying family members—face steep odds unless they meet a specific exemption or obtain a rare waiver. Iran has signaled it may rely on virtual participation if key officials are unable to attend in person, echoing past years when travel restrictions led to remote speeches or reduced delegations.
UN obligations and the security exception
The United States 🇺🇸 hosts the UN headquarters and is bound by the 1947 UN Headquarters Agreement to facilitate entry for representatives of UN member states. However, national security exceptions exist and have been used before to delay, limit, or deny entry for certain individuals. The 2025 policy intensifies this dynamic: even where categories are technically exempt, security checks are deeper and timelines less predictable.
In practice, that means travel approval for Iranian officials may come late, include restrictions on movement, or not arrive at all. Legal specialists note that the Immigration and Nationality Act grants wide discretion to the executive branch in deciding who may enter. They also point out that while the Headquarters Agreement imposes obligations, U.S. authorities can still deny entry on security grounds. Courts have historically upheld similar executive actions related to national security, so analysts expect legal challenges to the current proclamation could face an uphill battle.
Iran’s government has condemned the measures, arguing they breach international obligations and hamper diplomacy. UN officials have expressed concern about reduced access for member state delegations while acknowledging the host country’s legal room to act on security grounds. According to analysis by VisaVerge.com, the clash between host country discretion and the need for broad participation at high-level events is unlikely to resolve cleanly before the 2025 session.
Human impact and affected groups
For families and communities, the human impact is immediate:
- Iranian Americans hoping to bring parents to the United States may still proceed if the U.S. citizen relationship is clear and well documented.
- Siblings and adult children of U.S. citizens are outside the carve-out and will face denial.
- Couples engaged across borders face heartbreak as K-1 fiancé(e) visas are explicitly not exempt.
- Students admitted to U.S. programs must defer plans unless they hold another qualifying passport.
- Even for diplomatic travelers, uncertainty around processing times and security checks can disrupt plans and complicate UNGA schedules.
Advocacy groups caution that the visa suspension can strain diaspora families and deepen mistrust. Academic and policy analysts add that the proclamation resembles, and in some respects expands upon, earlier travel bans from 2017–2021, narrowing available exceptions and producing longer delays even within exempt categories. Many observers expect the framework to stay in place through at least the 2025–2026 UNGA cycle unless there is a major shift in U.S.-Iran relations.
Process for UN-related applicants from Iran
Officials emphasize a structured process for UN-related applicants from Iran:
- File for the appropriate
A
,G
,C-2
, orC-3
visa category. - Undergo rigorous security vetting by the Department of State, with input from the Department of Homeland Security and, if needed, the Department of Justice.
- Await a determination, with possible approval on a case-by-case basis where travel is deemed in the U.S. national interest.
Important: Approvals are not automatic and can be delayed or denied even for exempt categories. Applicants should plan for extended timelines and possible restrictions on movement.
Geopolitical context and commentary
The policy arrives amid heightened tensions, including the 2025 Iran-Israel conflict and ongoing concerns about Iran’s regional activities and nuclear program. Policymakers argue that tightening entry controls reduces risk; critics say it chills diplomacy and constrains multilateral problem-solving when dialogue is most needed.
Many experts note:
- The proclamation tightens controls at a time when global crises may require robust diplomatic engagement.
- The policy could limit face-to-face diplomacy at the UN just when multilateral forums are needed to address complex conflicts.
- Legal challenges are possible but uncertain given historical deference to executive national security judgments.
Practical advice for affected parties
What can affected parties do now?
- For government travelers: Build extra time into itineraries and prepare complete documentation for the chosen visa category.
- For families: U.S. citizens sponsoring a spouse or parent should compile strong evidence of the relationship and be ready for extended processing.
- For students and visitors with only Iranian passports: Prepare for virtual engagement or alternate destinations unless a rare waiver is granted.
- For delegations: Coordinate closely with the UN Protocol and Liaison Service and with U.S. visa authorities to track processing and requirements.
For official updates on visa processing policy and security screening, consult the U.S. Department of State – Visa Services. Delegations should also coordinate closely with the UN Protocol and Liaison Service for procedural guidance related to UNGA attendance and travel arrangements under current restrictions.
Key takeaways
- The United States has enacted a broad visa suspension for Iranian nationals, effective June 9, 2025, with narrow exemptions and tough security review.
- Attendance at UNGA will depend heavily on whether an applicant already holds a qualifying visa, meets limited family exceptions, or secures a rare, case-by-case approval tied to U.S. national interest.
- As the UNGA approaches, the difference between attending in person or speaking from afar may be determined by documentation, timing, and the outcome of rigorous security vetting.
This Article in a Nutshell
On June 9, 2025, the U.S. implemented a comprehensive visa suspension for Iranian nationals across immigrant and nonimmigrant categories, following a Presidential Proclamation. While diplomatic and UN-related visa categories (A, G, C-2/C-3) remain formally exempt, applicants must undergo rigorous interagency security reviews that can delay or deny entry. New visas in common categories like B, F, J and M are effectively halted. Family exceptions are narrowly drawn—spouses and parents of U.S. citizens may qualify with strong proof, but K-1 fiancé(e) visas are excluded. Visas issued before June 9 remain valid, and dual nationals traveling on non-Iranian passports are not subject to the suspension. The policy creates significant uncertainty for Iran’s UNGA 2025 delegation and could force increased virtual participation. U.S. legal authorities and the 1947 UN Headquarters Agreement leave room for national security denials, so legal challenges face high hurdles.
