This is the Immigration and Citizenship Data page of the U.S. Citizenship and Immigration Services (USCIS) website. The Tools and Resources available through this page include: petitions, applications, and other important immigration and citizenship forms. "USCIS receives and adjudicates approximately 6 million petitions and applications annually from individuals and employers. These petitions and applications typically allow foreign nationals to stay in United States as lawful permanent residents (LPR) or immigrants, to stay temporarily to work as nonimmigrants for some other purpose, or to obtain U.S. citizenship. These reports generally provide summary data on the number of applications or petitions received, approved, denied and pending. In addition, certain tables list the USCIS office responsible for the adjudication. For Information on the number and characteristics of persons granted LPR and citizenship status, please refer to data and reports published by the DHS Office of Immigration Statistics at http://www.dhs.gov/Immigration-statistics. Additionally, see the Electronic Reading Room for frequently requested statistics. The information on this page is organized based on the benefits provided to individuals: 1) Family Based; 2) Employment Based; 3) Humanitarian; 4) Citizenship and Naturalization; 5) Frequently Requested Statistics; 6) All Forms; and 7) Archives."
