Quarter-over-quarter highlight: The pile of pending N-600 applications at USCIS grew 8% to 57,163 in Jan–Mar 2026. At that quarter's pace of decisions, clearing it would take 15 months, up from 14 months.

What happened to the applications

The bars are the N-600 decisions USCIS made each quarter, approved in blue and denied in red. The amber line is the backlog: how many applications were still waiting at the end of that quarter, most of them filed in earlier ones. The dashed line is how many came in.

How long the wait is

The estimated wait is how long it would take to decide every pending application if USCIS kept up that quarter’s pace. USCIS's own median processing time only counts cases already decided, so it reacts to a slowdown a quarter or two later.

The estimated wait is the pending applications at the end of each quarter, divided by the decisions (approvals and denials) made per month during it. USCIS's median is how long the cases it decided in the quarter had taken.
