Immigration Laws, Regulations and Guides

Welcome to the Immigration legal page. This page provides information on laws, regulations and interpretations controlling immigration and the work of the immigration-related bureaus of the Department of Homeland Security. You can explore agency and judicial interpretations of those laws. You can also find handbooks and guides used by immigration officers in performing their mission as well as guides created to help you through the immigration process.

The mission of the Office of USCIS Chief Counsel is to provide legal advice to immigration officials concerning issues that arise in conjunction with their performance of their official duties. (8 CFR 100.2(a)(1) and 103.1(b)(1).) There have been rare cases in which a particular program is of such general interest and importance that the Office of Chief Counsel has rendered a formal legal opinion. As a matter of policy, we have determined that providing legal opinions to private parties in matters that may come before immigration officials is inappropriate. For this reason, we are unable to express an opinion on the issues submitted by the public.
