In the fall term of the sophomore year, all license-track cadets who have completed their freshman sea term are required to apply for a Merchant Mariner Credential, commonly referred to as MMC. A valid MMC is required of all U.S. citizens and permanent residents of the U.S. to sail upon a U.S. flagged vessel. Cadets are required to possess a valid MMC with Cadet ratings to complete Sea Training II-Commercial Sea Term. Sophomore license-track cadets will be contacted once their entry level application timeline has been determined.
