A detailed report by the Iranian parliament's Research Center says the verification of any US removal of sanctions on Tehran would require at least three months, emphasizing that the process would not be possible within hours or days.
“It is obvious that the real test of sanctions removal and fulfillment of measurable indices put forward by Iran is not possible in a matter of few hours or days, and would take at least 3 to 6 months. It is also necessary to verify within specified intervals (for example every six months) that the Iranian economy benefits from the removal of the sanctions,” the parliament’s Research Center (IPRC) said in its report.
The report said Article 6 of the Strategic Action Plan to Counter Sanctions, a law passed in December by Iranian legislators, stipulates several general criteria concerning the removal of the anti-Iran sanctions.

They include normalization of banking transactions, total removal of export barriers, unhindered sale of Iranian petroleum and oil derivatives, in addition to complete and rapid return of revenues from Iranian oil sales.
