1.1 Purpose

The United States Citizenship and Immigration Services (USCIS) Office of Facilities and Space Management Branch have prepared this document with the specific purpose of setting standards for MDF / Computer and Telephone – LAN Rooms and Equipment. This document will be used to provide the following:

• Facilitate the planning and installation of MDF / Computer and Telephone – LAN Rooms and Equipment.

• To ensure uniformity of MDF / Computer and Telephone – LAN Rooms and Equipment in all USCIS facilities.

The primary focus of this document is to define the standards for space, materials, infrastructure, design and installation for USCIS facilities. For questions or comments regarding this document, contact the USCIS Field Support Center Chief, Facilities and Space Management branch Chief at

(802) 872-4114.

1.2 Background

United States Citizenship and Immigration Services (USCIS) is a component of the U.S. Department of Homeland Security (DHS). The mission USCIS is to secure America's promise as a nation of immigrants by providing accurate and useful information to our customers, granting immigration and citizenship benefits, promoting an awareness and understanding of citizenship, and ensuring the integrity of our immigration system. Because of increasing demands on Service resources, USCIS personnel must be able to share information rapidly and efficiently in order to succeed in fulfilling the Service mission.

1.3 Scope

This document is intended to address the following responsibilities and specifications for all USCIS MDF / Computer and Telephone LAN Rooms and Equipment:

• Movement of Equipment.

• Installation of Cabling.

• Distribution of Telephones.

• Size of Rooms.

• Finishes for Rooms.
