from this FOX news article from 2018 - was later denied by all concerned but interesting…
"The Obama administration granted citizenship to 2,500 Iranians, including family members of government officials, while negotiating the Iran nuclear deal, a senior cleric and member of parliament has claimed.
Hojjat al-Islam Mojtaba Zolnour, who is chairman of Iran’s parliamentary nuclear committee and a member of its national security and foreign affairs committee, made the allegations during an interview with the country’s Etemad newspaper, cited by the country’s Fars News agency."
He claimed it was done as a favor to senior Iranian officials linked to President Hassan Rouhani, and he alleged the move sparked a competition among Iranian officials over whose children would benefit from the scheme.
There is no suggestion either of these people received citizenship in the wake of the Iranian nuclear deal. It’s also unclear if Zolnour meant citizenship or a green card.
In 2015, 13,114 people born in Iran were issued green cards, while 13,298 were issued one in 2016, according to figures from the Department for Homeland Security. In 2015, 10,344 Iranians became naturalized, with a further 9,507 in 2016.
