The USCIS mission statement is available on their website. It reads: "USCIS will 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.
"We are the 19,000 government employees and contractors of USCIS working at 223 offices across the world. Achieving our goals becomes possible when the different elements of our organization are engaged and acting as partners working toward a common outcome."
