What we will not show you

Every figure below is one people ask for constantly. None of them exists in public US data. We return nothing rather than an estimate.

Requested figureStatusWhy
F-1 refusal rate for India (or any one country)Not published Refusal rates by nationality exist for B visas only. By class, only a worldwide figure exists.
H-1B refusal rate by nationalityNot published Same gap. USCIS's H-1B Employer Data Hub carries no beneficiary nationality field at all.
Approval rate at a specific consulateNot published Monthly files exist by post and by nationality, but are never crossed — and neither carries refusals.
214(b) or 221(g) rate for a country or classNot published Refusal grounds are published globally with no class and no nationality split.
Any refusal figure at monthly frequencyNot published All monthly State Department files are issuances only.
H-1B lottery odds by nationalityNot published Selection rate is released as a single global number in a news post.
FY2017 and FY2018 nationality refusal ratesNever published Both PDFs return 404 at the source. Our charts break the line rather than interpolating.

The statute

8 U.S.C. § 1202(f) makes State Department and consular records on the issuance or refusal of visas confidential, with narrow exceptions for courts and for reciprocal law-enforcement sharing. It operates as a FOIA Exemption 3 withholding statute, so record-level requests are refused as a matter of course.

The three dimensions people want — refusal ground, visa class, nationality — are each published, but only as separate marginal tables. The cross-tabulation does not exist in any public US dataset. That is a publication decision, not a scraping problem, and no amount of engineering produces it.

Anyone displaying a per-country, per-class refusal rate is doing one of three things: mislabelling a worldwide figure as a national one, interpolating, or making it up.
