Individuals can apply for a Coast Guard Port Security Card; their application is evaluated on a number of factors before a Card is granted, and the Commandant may withhold approval of the application based on these factors. Likewise, a current holder of a Security Card may be deemed inimical to the security of the United States by the Commandant. In both cases, the Commandant gives notice to the applicant/holder, who may file a written answer including documents/evidence pertinent to the matter. If the Commandant is still unsatisfied, he may refer the case to a three-member Hearing Board chaired by an officer of the Coast Guard.
After the hearing, the Board submits a recommendation to the Commandant, who makes the decision whether to issue or withhold/withdraw a Security Card. Applicants/holders who receive an unfavorable ruling may appeal to an Appeal Board at Coast Guard Headquarters. The Appeal Board holds a hearing under the same procedures, and makes a recommendation to the Commandant, who makes the final decision.
