Director General of the International Atomic Energy Agency (IAEA) Yukiya Amano is scheduled to visit Iran on Sunday, Press TV reported.
The August 17 visit is aimed at discussing the issues regarding Tehran's nuclear energy program with Iranian officials.
The development comes ahead of the IAEA's August 25 deadline for Iran to provide the agency with a new set of information on its nuclear energy program.
On July 20, the IAEA's monthly report verified Iran's compliance with the terms of its interim nuclear deal with the five permanent members of the UN Security Council - the United States, Britain, Russia, France and China - plus Germany.
The Islamic Republic has eliminated its most sensitive stockpile of enriched uranium gas under the nuclear accord, the report included.
Iran has agreed to provide the IAEA with mutually agreed relevant information and managed access to the Saghand uranium mine in the city of Yazd and the Ardakan concentration plant.
Iran will also provide mutually agreed relevant information and arrange for a technical visit to Lashkar Abad Laser Center.
The country will further submit an updated Design Information Questionnaire (DIQ) for the IR-40 Arak heavy water reactor and take steps to agree with the IAEA on the conclusion of a Safeguards Approach for the IR-40 Reactor.
Iran and the IAEA signed a joint statement in November 2013 to outline a roadmap on mutual cooperation on certain outstanding nuclear issues. Under the deal, Iran agreed, on a voluntary basis, to allow IAEA inspectors to visit the Arak heavy water plant and the Gachin uranium mine, south of Iran.
