Iran-US Tensions 2026: What It Means for Travelers & Expats

In brief

The US president has issued direct threats to destroy Iranian power plants and bridges, framing the warning in the context of a potential closure of the Strait of Hormuz — a critical global shipping corridor. Foreign nationals currently in Iran or planning to travel there face heightened uncertainty across infrastructure, communications, and border access.

The security situation around Iran has shifted sharply. Rhetoric between Washington and Tehran has moved beyond diplomatic posturing: the US administration has explicitly named Iranian civilian infrastructure — including electrical grids and transport bridges — as potential military targets. For the estimated tens of thousands of foreign nationals living or traveling in Iran, this escalation is not an abstraction. It is a direct concern affecting safety, mobility, and daily life.

What Exactly Was Threatened — and Why It Matters to You

The US president's statements specifically referenced power plants and bridges as potential strike targets, tying the threat to Iran's posture over the Strait of Hormuz — the narrow waterway through which roughly 20% of the world's oil supply passes. Iranian officials have, in the past, floated the idea of closing the strait during periods of maximum pressure.

For anyone on the ground in Iran, the practical implications of even partial infrastructure damage would be severe:

Power outages: Strikes on energy infrastructure could cause widespread, prolonged blackouts affecting hospitals, water pumping stations, communications networks, and ATMs.

Disrupted transport: Bridges are critical to road networks across a geographically complex country. Their destruction would isolate entire regions.

Banking and communications breakdown: Iran's internet infrastructure and financial systems rely heavily on centralized hubs — these are particularly vulnerable during conflict escalation.

⚠️ Attention

No military action has been confirmed at the time of publication. However, the severity of the rhetoric warrants immediate contingency planning for any foreign national in Iran. Do not wait for an official attack to prepare your exit or shelter plan.

Hormuz Strait Closure: A Scenario With Global Ripple Effects

The Strait of Hormuz is not just a geopolitical flashpoint — it is an economic lifeline for the region. A closure or sustained military presence in the strait would:

Disrupt fuel supplies across Iran and neighboring Gulf states within days

Trigger sharp increases in fuel prices, affecting transport and food distribution inside Iran

Complicate international flight routes and potentially ground airlines operating near Iranian airspace

Cause cascading shortages in goods that Iran imports — including some medicines and electronics

For expatriates on long-term assignments or digital nomads spending extended time in Iran, a Hormuz closure scenario could rapidly transform a manageable situation into a full-scale evacuation emergency.

Immediate Steps for Foreign Nationals in Iran Right Now

1. Register with your embassy or consulate today

Every foreign national in Iran should be formally registered with their country's diplomatic mission. This is the fastest way to receive evacuation notices, emergency alerts, and consular assistance if the situation deteriorates. Contact your own country's embassy — not just the largest one — as procedures differ significantly by nationality. If your country does not maintain a direct embassy in Tehran, identify the third-country embassy designated to handle your nationals.

2. Prepare a go-bag and emergency cash

In any scenario involving power outages or banking disruptions, physical cash in a hard currency (USD or EUR) becomes essential. ATMs will fail if the power grid is damaged. Keep enough cash for at least 72 hours of food, transport, and potential accommodation outside of major cities. A go-bag with documents — passport, visas, emergency contacts, medical prescriptions — should be ready to grab within minutes.

3. Identify your exit routes now, not later

Iran shares borders with Turkey, Armenia, Azerbaijan, Turkmenistan, Afghanistan, Pakistan, and Iraq. Depending on your nationality and the direction of any conflict, some of these crossings will be safer than others. Research which border crossings are currently open, what documents you need, and whether your country has any travel advisories warning against specific overland routes. Do this research before an emergency, not during one.

What Travel Advisories Are Saying in 2026

Multiple governments — including the United States, United Kingdom, Canada, Australia, and several EU member states — already maintained "do not travel" or "reconsider travel" advisories for Iran before this latest escalation. The current threat level has prompted several missions to quietly reinforce crisis protocols. Key facts to know:

The US has no embassy in Iran; Swiss diplomats handle US consular interests in Tehran.

Several Western countries operate with skeleton staff or remote embassy arrangements in Iran.

Consular assistance in an active conflict scenario will be extremely limited — evacuation is not guaranteed and is never automatic.

Travel insurance policies almost universally exclude coverage for losses in active war zones — review your policy terms immediately.

Long-Term Residents: Protecting Your Assets and Legal Status

For expatriates on work visas, business assignments, or long-term residency in Iran, escalating tensions raise complex legal and financial questions. Currency controls in Iran were already severe before this crisis — sanctions and now the threat of military action will likely tighten those restrictions further. Consider the following:

Property and lease agreements: Understand what your contract says about force majeure clauses and what protections you have if you need to break your lease urgently.

Employment contracts: If your employer is based outside Iran, clarify your evacuation entitlements and whether your contract covers emergency repatriation.

Dual nationals: Iran does not recognize dual nationality for its own citizens. If you hold Iranian nationality alongside another passport, your situation is significantly more complicated — seek legal advice urgently.

For legal questions specific to your situation in Iran, connecting with a qualified local lawyer through a platform like SOS-Expat.com can provide clarity without requiring you to navigate local bureaucracy alone during a crisis.
