Grant-rate trend

Each point is the grant rate across the 12 months ending in that month — a rolling window, not a single month on its own. A point appears only where those 12 months hold at least 25 decisions. A rolling window covers a much shorter span than the lifetime figure above, so the two can differ materially; both are correct measures of different periods.

Source and method

These figures come from case data released by the Executive Office for Immigration Review (EOIR) under the Freedom of Information Act, published by the Deportation Data Project. Imigrar did not produce or estimate them.

Captured on September 18, 2026, about 0 months ago, so it is out of date. The record covers decisions from October 1997 through July 2026; nothing filed or decided after July 2026 appears here.

Grant rates are historical aggregates. They describe decisions already made. They do not predict the outcome of any individual case, and no figure on this page should be read as a forecast of what will happen in yours.

This page is informational only and is not legal advice. Reading it does not create an attorney-client relationship. Only the official EOIR record is authoritative.
