There are several voting centers throughout the United States where Iranians can vote in today's presidential election, according to the Iranian government. 

The official Islamic Republic News Agency reported on Wednesday that there are 27 polling stations in 18 states, including Washington, DC, for Iranian citizens to cast their ballots. Polls opened at 8:00 a.m. and will close at 6:00 p.m., according to the agency, which cited Iran’s ambassador to the United Nations Majid Takht Ravanchi. 

Iranians are voting for the successor of President Hassan Rouhani, who is term limited. Some Iranian analysts view the vote as between Reformist candidates, who have been hindered by the authorities, and conservative figures more favored by the Islamic Republic establishment. Low turnout is widely expected. Only candidates approved by Supreme Leader  Ayatollah Ali Khamenei can run. 

Iran and the United States lack formal diplomatic relations, and the Pakistani Embassy in Washington represents Iran in the country. Iran also has a mission at the UN headquarters in New York City, where Ravanchi is based.
