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.

The line is broken where this record has no decisions for several months. It is left open rather than joined, because joining it would imply decisions that were never recorded.

30 months are not plotted: the 12 months ending there held fewer than 25 decisions.

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 24, 2026, today. The record covers decisions from April 2005 through December 2013; nothing filed or decided after December 2013 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.
