MCI is a subsidiary of Verizon Communications. MCI Inc. was formed as a result of the merger between WorldCom and MCI Communications.
"This license authorized WorldCom to strike a deal by which the state-owned Telecommunications Company of Iran would pay the American telecommunications company a rental fee in return for a direct link to WorldCom's United States Internet backbone. OFAC said the application was approved because it would have provided increased and more consistent Internet access for Iranians, and it is the policy of the United States to encourage such access."
