Methodology and sources

Every dataset behind this site, with the agency that publishes it and a link to get it yourself. 44 come from federal statistical sources; 13 do not, and are marked.

This page is generated from the project's dataset catalogue, not written by hand, so it cannot fall behind what the site actually uses. A dataset added without a source URL fails the consistency checks.

Derived

These are built from the datasets above and have no external source: repo_datasets, expansion_phases, summary, live_bundle, site_map, chat_facts, parquet_exports, curated_answers, og_cards.

What the data cannot answer

Three limits recur and are stated wherever the figures appear. Cap-exempt status is not published: USCIS records it on the I-129 and releases only national totals by employer category, so every public cap-exempt employer list, including this site's, is an inference from employer type. IPEDS counts degrees, not people, so any progression figure is a ratio between two populations rather than a tracked cohort. And no federal source records graduate applications or admissions, so whether domestic applicants are declining, being declined, or not applying cannot be determined from published data.
