The USCIS site offers much for the researcher. The “Laws and Regulation” section provides “information on laws, regulations and interpretations controlling immigration and the work of the immigration-related bureaus of the Department of Homeland Security.”
The page provides links to settlements/agreements in class actions brought against the Agency. Another useful page is the subject listing of policies and procedures. The subject listing makes it easier to locate all related policies.
There are also a few items worth noting under the “About USCIS” tab. Look for reports, studies and statistics. The tab also includes the “Electronic Reading Room” which contains contracts, administrative decisions, handbooks and manuals.
The Board of Immigration Appeals (BIA) Interim decisions, back to the first volume, are located on the site. However, researchers also check the U.S. Department of Justice’s Virtual Law Library for additional decisions, guidance, and the BIA practice manual.
