How to Interpret These Judge Statistics
Among the largest nationality groups shown for this judge (fiscal years 2020–2026), the table highlights Mexico (1,962 decided, 5.7% grant rate), Guatemala (313 decided, 3.2% grant rate), and Venezuela (271 decided, 3.0% grant rate). Compare these rows with the judge's overall rate because nationality mix can materially change how the headline number should be read.
Grant rate is calculated as granted / (granted + denied). Other procedural outcomes, including terminated, withdrawn, administratively closed, or removed cases, are tracked separately where available and are not treated as asylum grants.
