1 Estimated admission totals rounded to the nearest hundred thousand. Excludes sea and air crew admissions (D1 and D2 visas).
2 Beginning in 2010, the number of I-94 admissions greatly exceeds totals reported in previous years due to a more complete count of land admissions.
3 Beginning in 2006, annual increases in H2A admissions may be due to more complete recording of pedestrian admissions along the Southwest border.
4 Issuances of H2R (returning H2B workers not subject to annual numerical limits) ceased at the end of 2007.
Notes: Admissions represent counts of events (i.e., arrivals) not unique individuals. Multiple entries of an individual on the same day are counted as one admission.
The majority of short-term admissions from Canada and Mexico are excluded.
