The Chicago Field Office is responsible for the states of Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin.


The office has approximately 40 Diplomatic Security special agents and investigators. These special agents and investigators form the backbone of DS' domestic law enforcement mission.


The principal investigative focus of the Chicago Field Office is maintaining the integrity of U.S. passports and visas. To accomplish this mission, the office works with Federal, State, and local law enforcement agencies, along with the U.S. Department of State's Bureau of Consular Affairs, to investigate any fraudulent use of a U.S. passport or visa.


The Chicago Field Office is also responsible for providing protective security to certain high-level foreign dignitaries when they are in the United States. In addition, the office provides protective security coordination for foreign diplomatic missions located within its respective geographic area of responsibility. This protection includes providing crime prevention and security related guidance to these facilities and assigned diplomatic personnel as appropriate.
