The Immigration and Nationality Act (INA) and Department of Homeland Security (DHS) policy guidelines form the foundation of the legal framework within which the Office of the Principal Legal Advisor (OPLA) operates. The INA establishes the regulations governing immigration, naturalization, and citizenship in the United States, thereby outlining the legal parameters that OPLA must follow.

DHS policy guidelines complement the INA by providing operational directives and procedures that ensure the enforcement of immigration laws. Together, these regulations dictate how OPLA advises on legal matters related to immigration cases, providing coherence and consistency in the application of immigration laws across various cases and scenarios. This regulatory framework is essential for maintaining order in the legal processes related to immigration matters, making it the most relevant and authoritative set of guidelines for OPLA's operations.
