If an air carrier is already an Air AMS participant but chooses to expand its Air AMS participation to additional ports, what must that carrier do?

The air carrier must notify the CBP port and its assigned client representative prior to expanding its Air AMS participation to additional locations.  The assigned client representative may establish a user record for the air carrier participant in that port upon receipt of confirmation that the port has acknowledged the commencement date of Air AMS participation.
