Tourism in Iran provides a range of activities from hiking and skiing in the Alborz and Zagros mountains, to beach holidays by the Persian Gulf and the Caspian Sea. The Iranian government has made efforts to attract tourists to various destinations in the country.
The government website advises visitors to "dress modestly" at all times, which for women means covering head, arms, and legs down to the ankles.
Afghans in Iran are citizens of Afghanistan who are temporarily residing in Iran as refugees or asylum seekers. They form the largest percent of the Afghan diaspora. The first wave of Afghans crossed into Iran after the start of the Soviet–Afghan War in 1979.
According to Afghanistan's Ministry of Refugees and Repatriation and the United Nations High Commissioner for Refugees (UNHCR), there were approximately three million Afghan citizens in Iran as of January 2023, most of whom were born and raised in Iran during the last four decades. They are under the care and protection of the UNHCR, and are provided time-limited legal status by Iran's Bureau of Aliens and Foreign Immigrant Affairs, without a path to obtain permanent residency. There are also about 600,000 Afghan tourists, travelers, merchants, exchanged students, regular or irregular migrant workers, and others. According to Hassan Kazemi Qomi, half of Iran's foreign investors are Afghans.
