January 8, 2016: In an announcement today, NMC emphasizes that Credential and Medical applications MUST be submitted to the Regional Examination Center and not directly to the National Maritime Center or any Coast Guard Office.  The applications may be submitted by mail, by fax, in person or, preferably, electronically.  Applications submitted directly to NMC “may” be returned to the applicant.  That some of these wrongly submitted applications have gotten through to NMC has led to rumors that all applications may and should go to NMC.  This is not the case.
