Title 46 › Subtitle II — Vessels and Seamen › Part E — Merchant Seamen Licenses, Certificates, and Documents › CHAPTER 75 — GENERAL PROCEDURES FOR LICENSING, CERTIFICATION, AND DOCUMENTATION › § 7507
The Secretary who oversees the Coast Guard can extend or reissue mariner licenses, certificates of registry, and merchant mariner documents. For licenses and certificates, the Secretary may extend an expiring one up to 1 year if needed to clear a processing backlog or because of a national emergency or natural disaster. The Secretary may also reissue an expiring license or certificate for up to 5 years only to make its expiration date match a merchant mariner document. For merchant mariner documents, the same rules apply: up to 1 year for backlog or emergencies, or up to 5 years only to match a license or certificate. Extensions can be given to individual mariners or to a specifically named group. If a credential is renewed (not extended under these rules), the new credential begins the day after the old one expires.
