DHS has published visa overstay report for 2017.
DHS has determined that there were 52,656,022 in-scope nonimmigrant admissions to the United States through air or sea POEs with expected departures occurring in FY 2017, which represents the majority of air and sea annual nonimmigrant admissions. 98.67% of the in-scope nonimmigrant entries departed the United States on time.
An overstay is a nonimmigrant who was lawfully admitted to the United States for an authorized period but stayed in the United States beyond his or her authorized admission period. Nonimmigrants admitted for “duration of status” who fail to maintain their status also may be considered overstays.
DHS classifies individuals as overstays by using the ADIS system to match departure and status change records to arrival records collected during the admission process.
