Customs and Border Protection
Data repository
CBP collects individual-level data on every person it arrests or expels at the border as well as on every person who arrives at a port of entry whom it deems inadmissible (most frequently asylum seekers). Border arrest data are collected by the Border Patrol; inadmissible arrivals data are collected by the Office of Field Operations. CBP maintains a detailed FOIA library with these datasets and others.
Latest CBP data release
The most recent release of data is from March 2025 for people deemed inadmissible at the border and September 2024 for encounters. We are actively seeking more recent updates.
Apprehensions at the border
This dataset includes every apprehension at the border. Before 2020, all border arrests were apprehensions, and these files therefore include all arrests for those years. With the onset of the Title 42 pandemic expulsions program, some border arrests led to expulsions, which CBP does not categorize as apprehensions.

Annual apprehensions with place of origin
This dataset includes each person’s city and state of origin, but it lacks precise dates for each apprehension (it shows only the fiscal year), limiting its use. The file names suggest that these files only contain family apprehensions, but they actually contain all apprehensions.
