This guide was written prior to the 2026 hostilities between the US, Israel and Iran and is no longer being updated regularly due to the fast-paced nature of the conflict. Non-essential travel to the broader Middle East region is not advisable due to the risks related to military action. Please consult official government travel advisories and exercise extreme caution before considering travel to the region.

Expats moving to Iran can expect to experience certain elements of culture shock. Religion plays an important role in everyday life in Iran, and expats will need to be sensitive to these cultural norms and adjust their lifestyle accordingly.

Those who take the time to learn about the local culture and engage with Iranians in a meaningful way will find their experience to be more rewarding.


Language barrier in Iran

Persian, or Farsi, is the official language of Iran. When in business and diplomatic circles, most people speak English well, but it is wise for expats doing business in Iran to arrange an interpreter.

Expats who learn basic phrases in the local language will find that their efforts will be appreciated and that they are more likely to be welcomed into Iranian society.


Religion in Iran

Islam is practised by almost all of the Iranian population, and it permeates all aspects of political, economic, social, and legal life in Iran. This is something expats will have to adapt to in their daily lives.

Expats in Iran will soon become familiar with the sound of the Islamic call to prayer – Muslims are expected to pray five times a day: at dawn, noon, afternoon, sunset and evening. In Iran, most businesses close on Friday, which is a holy day for Muslims. Many businesses and government offices close or reduce hours on Thursday as well, so expats will often experience a Thursday-Friday weekend.

During the holy month of Ramadan, Muslims fast from dawn to dusk, and many businesses operate on a reduced schedule. Expats aren’t expected to fast, but they must not eat, drink, smoke or chew gum in public.


Family in Iran

Family is central to social structures in Iran. The concept of family is more private in Iranian culture, and locals take special care to protect their female family members from outside influences.

Iranians take their family responsibilities very seriously. Most only have one or two children, but extended families remain large. It’s common for elderly relatives to be taken care of by the wider family circle at home.

Nepotism is quite apparent in business circles in Iran. That said, it is regarded positively in the sense that employers can be sure that they are hiring someone trustworthy.


Privacy in Iran

Iranians tend to see themselves as having two distinct identities, zaher (public) and batin (private). When they are in public, they conform to accepted modes of behaviour and may refrain from showing their personality. That said, among family and close friends, they will be more open and are more likely to share personal information, offer advice and provide support in general.  


Manners in Iran

Expats in Iran will soon get accustomed to the concept of taarof. This is a system of politeness that includes both verbal and non-verbal modes of communication. Iranians are reluctant to accept compliments, as humility is a highly valued attribute.

In adherence to taarof, expats should at least show some reluctance to accept gifts or invitations until the insistence becomes greater.


Dress in Iran 

The Iranian attitude to dress code is more casual than one might expect, but there are specific rules that need to be followed. Most important is the headscarf (known in Farsi as a roosari) for women, which should be worn at all times and must cover the hair, and ideally, the neck. A little bit of hair showing isn’t a problem, and many local women wear their roosaris perched far back. When visiting a mosque or shrine, a chador (a full-length covering) is usually required; these can typically be borrowed at the entrance.

Local women tend to wear loose, modest clothing, and expats should follow suit. Bare forearms are fine, but shoulders should be covered.
