After passing your captain’s license exam, you have one year to submit a complete application to the National Maritime Center (NMC) through the ASAP portal. The NMC, a division of the U.S. Coast Guard (USCG), reviews your application in three stages: Safety and Suitability, Medical Evaluation, and Professional Qualification. Processing typically takes four to six weeks, sometimes up to 90 days.
You passed the exam. That’s the hard part. Now comes the paperwork, and if you get it right the first time, you’ll have your Merchant Mariner Credential (MMC), the official name for a captain’s license, in hand within a matter of weeks. Get it wrong, and you could wait months.
At Mariners Learning System, we’ve seen more applications delayed by avoidable paperwork errors than by any other single cause. Here’s a step-by-step breakdown of the process so yours moves through without a hitch.
The captain’s license is issued by the National Maritime Center (NMC), a division of the U.S. Coast Guard based in Martinsburg, West Virginia. The NMC evaluates all applications for Merchant Mariner Credentials (MMCs) and issues credentials in compliance with 46 CFR Part 10, the federal regulation governing mariner credentialing. Although everyone calls it a “captain’s license,” the NMC refers to it officially as an MMC.
The NMC handles the full pipeline: background checks, medical review, sea-time verification, and credential printing. Your application doesn’t go to a local office; it goes directly to this centralized review center.
All captain’s licenses are MMCs, but not all MMCs are captain’s licenses. When you complete the application process, an MMC with your endorsed license will arrive in your mailbox.
As of January 2026, the NMC requires all applications to be submitted through the Application Submission and Additional Information Portal (ASAP). Email and fax submissions are no longer accepted and will be rejected.
Your application packet includes two separate submissions through ASAP:
MMC Application Packet (submitted under the MMC tab):
Medical Certificate (submitted separately under the Medical tab):
The MMC packet and the medical certificate are processed by different teams at the NMC. Submitting them together in one upload or mixing them up will delay both.
No. Character reference letters are no longer required. The Coast Guard eliminated this requirement years ago. Don’t waste time gathering them.
Once the NMC receives your application, it moves through three evaluation stages. Understanding what each stage checks will help you avoid the mistakes that trigger delays.
|
Review Stage |
What They Check |
Common Issues |
|
Safety and Suitability (SSE) |
Background check, TWIC data, NDR (driving record), criminal history |
Undisclosed convictions, TWIC not yet issued |
|
Medical Evaluation |
CG-719K completeness, provider qualifications, vision and hearing |
Missing signatures, unqualified examiner, incomplete form |
|
Professional Qualification (PQS) |
Sea time documentation, course certificate, endorsement eligibility |
Incorrect tonnage on CG-719S, expired certificate |
Your application can stall at any stage. If the NMC finds an issue, you’ll receive an “Awaiting Information” (AI) letter requesting additional documents. Each AI letter can add weeks to your timeline, so getting every detail right on the first submission is the fastest path to your credential.
For original applications, the NMC advises allowing up to 90 days, though complete, error-free packets typically process in four to six weeks. Peak season (spring and early summer) and incomplete applications are the two biggest causes of longer wait times. You can check your application status using the Merchant Mariner Application Status tool on the Coast Guard website.

Download every form directly from the NMC website or the Mariners Learning System resources page right before your appointment. Using an expired version of any form can invalidate your submission.
Check the expiration date printed in the upper right corner of each form. If the date has passed, download the newest version. The CG-719 series forms are periodically updated, and an outdated form is one of the most common rejection reasons.
The Coast Guard charges evaluation and issuance fees for MMC transactions, payable through Pay.gov. Fees vary by license type and transaction. For an original captain’s license application with a USCG-approved course (no separate exam fee), the total government fee is typically around $145, covering evaluation and issuance per 46 CFR 10.219. Save the email receipt from Pay.gov and include it in your application packet.
At Mariners Learning System, the exam is included in your course tuition with no separate testing fee. That $695 (OUPV/Six-Pack) or $895 (Master) covers the course and the exam. The Coast Guard’s evaluation and issuance fees, your physical, drug test, and TWIC costs are separate.
Once all three review stages approve your application, the NMC’s credential production team prints and mails your Merchant Mariner Credential via USPS. Make sure the mailing address on your CG-719B is a valid USPS address.
You can’t operate a vessel commercially until your credential is in hand. Plan your timeline accordingly, especially if you have a charter season or employment start date to hit.
Starting March 1, 2024, the Coast Guard issues MMCs in a new format, replacing the old passport-style red book. Legacy credentials remain valid until their printed expiration date. Your new credential arrives as a single document with all endorsements printed directly on it rather than as separate labels.
The application forms can feel overwhelming, especially for first-time applicants. Mariners Learning System can help answer basic questions about where to go and what to fill out, though we can’t complete your application for you.
As a student with us, you receive access to MM-SEAS Expert Access for two years at no additional cost with your captain’s license purchase. MM-SEAS provides expert guidance, interactive checklists, and unlimited one-on-one video calls with USCG licensing specialists. Valued at $198, this service is included free with a purchase of our captain’s license course.
You can begin assembling your forms (physical, drug test, TWIC, sea time) before completing the course. But you can’t submit the packet to the NMC until you have your Certificate of Completion from passing the exam.
The NMC will send you an Awaiting Information (AI) letter specifying what’s missing. Respond promptly. Each AI cycle adds weeks to processing. The simplest way to avoid AI letters is to review your entire packet against the NMC checklist before hitting submit.
Yes. Third-party services will review your packet for completeness and submit it on your behalf. This option is most common among applicants with unconventional situations, like medical waivers, foreign sea time, complex criminal histories, or military service documentation.
Passing the exam was the hard part. The application process is straightforward once you know the forms, the portal, and the deadlines. Prepare your documents in parallel, double-check every signature, and submit a clean packet through ASAP. That MMC will be in your mailbox before you know it.
If you have questions about the application process or any other part of earning your captain’s license, the team at Mariners Learning System is here to help. We’ve guided more than 200,000 students through this process, and we’re not going to let paperwork be the reason you don’t get your license.
Regulations, fees, and submission methods change. The NMC transitioned to ASAP as of January 2026 and no longer accepts email or fax submissions. Confirm all requirements with the National Maritime Center before submitting your application.
