The visit by International Atomic Energy Agency head Amano is aimed at resolving the decade-long standoff over Iran's disputed nuclear programme.
The West suspects Iran of trying to develop nuclear weapons, but Tehran says the programme is for peaceful purposes only.
"I invited Amano to visit Tehran on November 11 and he expressed his willingness to come," Salehi was quoted as saying by the website of state broadcaster IRIB.
Salehi said he hoped "to reach an agreement with (Amano) and issue a joint statement".
