Trends

Filing dates checked through 2026-09-02. All-time corridor context: 98,829 families · Median to foreign filing 147 days. These two context values cover all available years. Selected-period corridor peak: 2025, 4,700 observed families.

Origin counsel coverage for 2017–2026: 27,890 of 34,780 families filed in these years carry a resolved outside-counsel organization on the origin member (80.2%, most of the denominator). The remainder is not charted. A family filed through two counsel on the same side counts once under each, so the stacked bands total more than the families behind them. The two sides list different firms: a firm that mainly receives work in this corridor appears on the destination side, not here.
