Having failed to revive a 2015 Iran nuclear deal, Washington hopes to restore some limits on Iran to keep it from getting a nuclear weapon that could threaten Israel and trigger a regional arms race.
An Iranian official said: "Call it whatever you want, whether a temporary deal, an interim deal, or a mutual understanding - both sides want to prevent further escalation."
U.S. Special Envoy for Iran Rob Malley has also met Iran's ambassador to the U.N. after months of Iran refusing direct contact.
The Western official said the key U.S. objective was to keep the nuclear situation from worsening and to avoid a potential clash between Israel and Iran.
U.S. House Foreign Affairs Committee Chairman Michael McCaul, a Republican, wrote to President Joe Biden on Thursday saying "any arrangement or understanding with Iran, even informal, requires submission to Congress".
