26 judges

Lists are ordered by number of decisions, not by grant rate: a best-to-worst ranking of this data would mislead.

EOIR data through August 31, 2026 · built September 11, 2026 · What these dates mean

Judges with fewer than 50 decisions are not listed: at that sample size the percentage is noise rather than a characteristic. Their pages still open by direct link.

How this percentage is calculated

Grant rate = granted / (granted + denied). Administrative closures, withdrawals, abandonment and "not adjudicated" are excluded from the denominator. What is counted is a decision per proceeding, not per application: asylum, withholding and CAT protection are almost always asked for together, so withholding and CAT grants are counted separately from asylum. The U.S. fiscal year runs October 1 – September 30.
