This is a collection of data from the U.S. Customs and Border Protection (CBP), primarily about apprehensions of illegal immigrants. All the data here was originally scraped from the PDFs available from the U.S. Customs and Border Protection's Stats and Summaries page on their website (https://www.cbp.gov/newsroom/media-resources/stats). I am in no way affiliated with CBP. What I did was take their public files and scrape the tables in the PDFs to make them more accessible. I then combined some tables together and reshaped the data to make it easier to use for analysis. The data is now available in R, Stata, and Excel (.csv) formats.
Please note that all the data is in fiscal years (October-September), not in calendar years.
There are 8 files and they all contains different information and some contains different number of years. Below is the file name, a brief description, the years of data available, and which variables it has, for each file.

This study is an evaluation of the "fast-track" program that was created to alleviate caseload pressures caused by a dramatic increase in immigration-related cases. This program allows a federal prosecutor to offer a below guideline sentence in exchange for a defendant's prompt guilty plea and a waiver of certain rights. Research questions addressed in the study included: (1) to what extent do fast-track programs impact the efficient processing of (primarily) immigration cases and (2) to what extent does prosecutorial discretion exercised in fast-track processing contribute to sentencing disparity.

For its inaugural year, the survey concentrated on issues such as: illegal versus legal immigration, admission criteria preferences, enforcement tactics, international cooperation on immigration policies, immigration and security, national identity, assimilation versus multiculturalism, and the compatibility of Islam and Western society. Several questions were also asked pertaining to voting and politics including whether respondents discussed political matters with friends, and whether they attempted to persuade others close to them to share their views on politics which they held strong opinions about, vote intention, assessment of the current United States presidential candidates, political party attachment, and left-right political self-placement. Demographic and other background information includes age, gender, ethnicity, citizenship, origin of birth (personal and parental), marital status, religious affiliation, age when finished full-time education and stage at which full-time education completed, occupation, type of locality, and region of residence.
