"The U.S. Immigration Court system is currently staring up a mountain of pending cases that at the end of December 2021 reached 1,596,193 — the largest in history. If every person with a pending immigration case were gathered together it would be larger than the population of Philadelphia, the sixth largest city in the United States. Previous administrations — all the way back through at least the George W. Bush administration — have failed when they tried to tackle the seemingly intractable problem of the Immigration Court "backlog."
