Can a person in the United States, who has not been designated as the U.S. agent for a foreign facility, perform the registration function for that facility?

Registration must be performed by the owner, operator, or agent in charge of a facility, or an
individual authorized to register the facility by one of them (21 CFR 1.225 and 1.230). The
authorized individual may be, but is not required to be, the U.S. agent for the facility
