I've had my Maryland Fishing Guide and Coast Guard license since 1990 . I am in the process of renewing it .I've completed the Coast Guard physical , Drug test, Criminal Record and Sea time . I was going to schedule an appointment to renew my Transportation Workers Identification Credential TWIC card . I called the TWIC center on Broening Hwy. No answer, dead number. I think they are closed? Anyway, on the renewal application, it states I can check the exempt box for my credential and bypass this procedure . It also states that by checking the box, could "Significantly' delay the processing of my Merchant Mariner Credential Renewal Application . Have any of you Captains checked this exempt box and if so, what was your time delay for getting your credential? TIA
