The court-wide lifetime rate is a stable historical benchmark; this judge's trailing 12-month rate uses the same methodology but a shorter window, so the two values can differ materially.
Over the trailing 12 months, Immigration Judge Peterson, William C. granted asylum in 10.0% of decided merit cases at the Boston Immigration Court, based on FOIA-released EOIR data. The figure uses the standard methodology: cases granted divided by cases granted plus cases ordered removed.
The lifetime grant rate weighted across all judges at the Boston Immigration Court is 52.0%. Per-judge rates can diverge from the court-wide aggregate because of caseload mix, time on the bench, and the 2025 asylum-policy shift that changed merit-decision volumes nationally.
10 merit asylum decisions appear in the FOIA-released EOIR data for Judge Peterson, William C.. Administrative outcomes (terminations, dismissals) are excluded from the rate.
No. The grant rate is a statistical aggregate over completed decisions, not a prediction. Individual case outcomes depend on case-specific merits, evidence, country conditions, and the quality of counsel. This page is informational and does not constitute legal advice.
