We are putting it into this one because of the business of the agency. They usually require that three members be available to hear any complaint, and that three members be there to sign off. If the members are spread throughout the country you always have to require them to meet somewhere. Having them come to the national capital regional facility will mean that they are here and that they're all available to hear the evidence that the agency personnel present to them, and that they can discuss and sign off on the decisions there. Otherwise, they can continue what they're doing today, but it will take them longer to make decisions and sign the documentation.
Residence in the national capital region would be required only while they were members. That would not preclude them from maintaining a long-term residence elsewhere.
