8 C.F.R. § 1292.15
Upon approving an initial request for recognition or a request for renewal of recognition, or at any other time, the Assistant Director for Policy (or the Assistant Director for Policy's delegate), in the Assistant Director for Policy's (or the Assistant Director for Policy's delegate's) discretion, may extend the recognition of an organization to any office or location where the organization offers services. To request extension of recognition, an organization that is seeking or has received recognition must submit a Form EOIR-31 that identifies the name and address of the organization's headquarters or designated office and the name and address of each other office or location for which the organization seeks extension of recognition. The organization must also provide a declaration from its authorized officer attesting that it periodically conducts inspections of each such office or location, exercises supervision and control over its accredited representatives at those offices and locations, and provides access to adequate legal resources at each such office or location. The Office of Policy may require an organization to seek separate recognition for an office or location of the organization, for example, when a subordinate office or location has distinct operations, management structure, or funding sources from the organization's headquarters. The Assistant Director for Policy's (or the Assistant Director for Policy's delegate's) determination to extend recognition to the offices or locations identified in Form EOIR-31 permits the organization's accredited representatives to provide immigration legal services out of those offices or locations. The Office of Policy will post the address of each office or location to which recognition has been extended on the roster of recognized organizations and accredited representatives. The Assistant Director for Policy (or the Assistant Director for Policy's delegate) is authorized to allow requests and determinations described in this section to be made electronically.
