A White House official said Obama would see Ahmad al-Jarba while the opposition leader is in Washington for meetings with Secretary of State John Kerry and other US officials. The exact day of Obama's meeting was unclear, though it's likely to occur after the president returns from a three-day trip to the West Coast that kicks off tomorrow.
The official insisted on anonymity in order to confirm Obama's meeting before it was publicly announced.
The administration recognised the opposition council as the legitimate representative of the Syrian people in December 2012, but its US offices had been recognised only as informal liaison bureaus until this week.
The moves come at a critical time in the conflict as Assad's government has made recent battlefield gains and is planning presidential elections in June. The administration is considering taking additional steps in the coming days, including the possibility of levying new sanctions on the Assad regime.
The White House has denounced the June presidential elections in Syria as a farce aimed at giving Assad the veneer of electoral legitimacy. Assad has ruled Syria since 2000, when he took over from his late father.
