Yes, Orlando International Airport (MCO) has full U.S. Customs and Border Protection (CBP) facilities to process international arrivals. If you are arriving on an international flight, you must clear immigration (passport control) and customs before entering the United States. In Terminal C, the process follows a "bags first" model where you collect checked luggage before proceeding to immigration. In Terminals A and B, you typically clear immigration first, then collect your bags for a final customs check. Eligible travelers can use the Global Entry kiosks or the Mobile Passport Control (MPC) app to speed up the process. It is important to note that if Orlando is your first point of entry into the U.S. and you have a connecting domestic flight, you must clear immigration, collect your bags, clear customs, and then re-check your luggage at the transfer desk before heading to your next gate.
