The U.S. State Department announced Saturday that it has revoked the green cards of three Iranian nationals and placed them in Immigration and Customs Enforcement custody.

The individuals are Seyed Eissa Hashemi, his wife Maryam Tahmasebi, and their son. Federal agents arrested the three after the State Department terminated their legal permanent resident status.

According to State Department officials, Hashemi's mother was an Iranian revolutionary who served as a spokesperson for Iran's regime during the 1979 hostage crisis at the U.S. Embassy in Tehran. The crisis, which lasted 444 days, occurred during the final year of President Jimmy Carter's administration.

The action comes one week after authorities arrested two relatives of Qasem Soleimani, the Iranian military commander who was killed in a U.S. drone strike in 2020. The State Department has not provided additional details about the specific reasons for revoking the green cards.

Green card holders, also known as legal permanent residents, typically have the right to live and work permanently in the United States. The revocation of such status is uncommon and usually involves national security concerns or immigration violations.
