Definition
INA is the standard abbreviation for the Immigration and Nationality Act, the foundational federal statute governing immigration, naturalization, and the conditions under which foreign nationals may enter, remain in, or be removed from the United States. Originally enacted in 1952, the INA consolidated and reorganized prior immigration law into a single comprehensive code. It has been substantially amended multiple times, most significantly in 1965 (eliminating the national-origins quota system), 1986, 1990, and 1996. The INA defines categories of admissible and inadmissible aliens, establishes visa classifications, sets procedures for asylum and refugee status, governs naturalization requirements, and provides the legal framework for removal proceedings. It is codified at Title 8 of the United States Code, though practitioners and courts routinely cite INA section numbers rather than U.S.C. citations, creating a dual-citation system that requires attention in research.

Why It Matters in Research
The INA is the central statutory axis of U.S. immigration law, and nearly all administrative and judicial immigration decisions are anchored to specific INA provisions. Researchers face a persistent citation translation problem: courts, agencies, and advocates routinely cite INA section numbers (e.g., INA § 212, INA § 237, INA § 245), while the codified law appears under 8 U.S.C. with different numbering. A cross-reference table is essential when working across sources from different eras or contexts.
The statute's amendment history is particularly consequential. The INA as enacted in 1952 reflects Cold War-era policy priorities, including ideological grounds of inadmissibility, that were later modified or repealed. Sources written before 1965 describe a quota system that no longer exists; sources written before 1996 do not reflect the significant expansion of mandatory detention and expedited removal introduced by the Illegal Immigration Reform and Immigrant Responsibility Act (IIRAIRA). When consulting secondary literature or older legal memoranda, it is critical to identify which version of the INA is being discussed.
The Board of Immigration Appeals (BIA) and the federal circuit courts have developed extensive case law interpreting INA provisions, and circuit splits on key questions are common. Research into INA-based claims must account for which circuit's law applies, as outcomes on issues such as the definition of "particularly serious crime" or the scope of the "persecutor bar" can vary substantially by jurisdiction.
The INA also intersects with constitutional law (due process in removal proceedings, First Amendment associational rights), administrative law (Chevron deference to BIA interpretations, now subject to the post-Loper Bright framework), and international refugee law (the 1951 Refugee Convention as implemented through the INA's asylum provisions). Researchers moving between immigration-specific and general legal sources should be attentive to these intersections.

Historical Dictionary Support
Burrill's Law Dictionary does not contain an entry for INA. The abbreviation and the statute postdate Burrill's publication by nearly a century. The passage cited from Burrill in the source material — referencing Coke on the inadvisability of self-counsel — bears no connection to this term and appears to reflect a corpus indexing artifact rather than substantive dictionary content. Researchers should not rely on Burrill or other nineteenth-century legal dictionaries for any guidance on the INA or modern immigration law concepts. The historical legal dictionary shelf is effectively silent on this term.

Jurisdictional Note
The INA is a federal statute of uniform national application, but its interpretation varies significantly across the federal circuits. The Ninth, Second, and Fourth Circuits have developed particularly extensive immigration jurisprudence that diverges on key questions from other circuits. Administrative interpretations by the BIA are subject to varying levels of deference depending on the interpretive question and the applicable circuit.
