BIA Edge

BIA Edge is a retrieval layer that gives AI agents citation-grade access to the U.S. immigration-law corpus. It covers published BIA precedent plus roughly 248,000 unpublished BIA decisions and 167,000 AAO non-precedent decisions, federal circuit, district, and Supreme Court immigration cases, Attorney General and OCAHO decisions, the INA and Title 8 and related CFR, the USCIS Policy Manual, FAM and agency guidance, state and federal criminal codes for crimmigration screening, visa bulletins, and EOIR statistics. Its read-only tools cover exact citation lookup, case and statute search, case-validity and treatment signals, unpublished and immigrant-favorable decision search, doctrine and related-precedent context, pinpoint source-text passages, and state and federal criminal-code screening. BIA Edge is a corpus-and-retrieval layer designed for the agent to verify source text and synthesize the work product; it does not produce final legal conclusions on its own. Built for immigration attorneys and the AI tools they already use. Access requires a BIA Edge account (request at https://biaedge.com/mcp-access); authentication is OAuth or an issued API key. The corpus is updated continuously, and freshness is reported through a corpus-status tool.
