unless the applicant's employer satisfies all of the requirements of § 12.805 of this subpart.

§ 12.805 Employer requirements.
(a) The employer must submit the following to the Coast Guard, as a part of the applicant's MMC application,
on behalf of the applicant:

not limited to, violence or assault, theft, drug and alcohol policy violations, and sexual harassment,
along with an explanation of the criteria used by the employer to determine the materiality of those
actions.
(2) A signed report regarding an employer-conducted background check. The report must contain—
(i)

A statement that the applicant has successfully undergone an employer-conducted background
check;

(ii) A description of the employer-conducted background check, including all databases and
records searched. The background check must, at a minimum, show that the employer has
reviewed all information reasonably and legally available to the owner or managing operator,
including the review of available court and police records in the applicant's country of
citizenship, and any other country in which the applicant has received employment referrals, or
resided, for the past 20 years prior to the date of application; and
(iii) All information derived from the employer-conducted background check.
(3) An employer-conducted background check, which must be conducted to the satisfaction of the
Coast Guard for an MMC to be issued to the applicant.
(b) If an MMC is issued to the applicant, the report and information required in paragraph (a)(2) of this
section must be securely kept by the employer on the U.S.-flagged large passenger vessel on which the
applicant is employed. The report and information must remain on the last U.S.-flagged large passenger
vessel on which the applicant was employed until such time as the MMC is returned to the Coast Guard in
accordance with paragraph (d) of this section.
(c) If an MMC or a Transportation Worker Identification Credential (TWIC) is issued to the applicant, each
MMC and TWIC must be securely kept by the employer on the U.S.-flagged large passenger vessel on
which the applicant is employed. The employer must maintain a detailed record of the seafarer's total
service on all authorized U.S.-flagged large passenger vessels, and must make that information available
to the Coast Guard upon request, to demonstrate that the limitations of § 12.811(c) have not been
exceeded.
(d) In the event that the seafarer's MMC and/or TWIC expires, the seafarer's visa status terminates, the
seafarer serves onboard the U.S.-flagged large passenger vessel(s) for 36 months in the aggregate as a
nonimmigrant crewmember, the employer terminates employment of the seafarer, or if the seafarer
otherwise ceases working with the employer, the employer must return the MMC to the Coast Guard and/
or the TWIC to the Transportation Security Administration (TSA) within 10 days of the event.
