USCG Medical Certificate Req Jan 24th

When will doctors have the new USCG procedures and forms and begin actually doing the new physicals? Once this system is up and running will doctors issue a “provisional” certificate on the spot, that will then be followed by NMC review, and hopefully by a regular certificate from the NMC some months later?

Is the USCG seeking reciprocity with other countries for the new medical certificates? Specifically, will the new USCG certificate be accepted by the UK MCA as an equivalent to the ENG1?
