How USCIS describes these numbers: “We generally process cases in the order we receive them. This processing time is based on how long it took us to complete 80% of adjudicated cases over the past six months. Each case is unique, and some cases may take longer than others. Processing times should be used as a reference point, not an absolute measure of how long your case will take to be completed.”
