The short answer is arithmetic. In FY2026 Q2 USCIS received 2,135,145 applications and finished 1,510,594. When more arrives than leaves, the pile grows, and the pile is now 12,129,905 cases.

at the close of the quarter
At the rate USCIS was clearing work last quarter, the pending pile alone represents about 8.0 quarters — roughly 2.0 years of output, before counting anything filed tomorrow.
Where the pile actually sits
It is not spread evenly. A handful of forms carry most of it, and they are not the forms most people are filing.
