The Immigration Court's active backlog of cases just passed the million case mark. The latest case-by-case court records through the end of August 2019 show the court's active case backlog was 1,007,155. If the additional 322,535 cases [1]which the court says are pending but have not been placed on the active caseload rolls are added, then the backlog now tops 1.3 million.

During the first eleven months of FY 2019, court records reveal a total of 384,977 new cases reached the court. If the pace of filings continues through the final month of this fiscal year, FY 2019 will also mark a new filing record.

While much in the news, new cases where individuals have been required to "Remain in Mexico" during their court processing currently make up just under 10 percent (9.9%) of these new filings. These MPP cases comprise an even smaller share - only 3.3 percent - of the court's active backlog.
