How long is my form taking?
USCIS publishes a range per form and per office. Both matter — the same form can differ by months depending on where it is being handled.
Forms decided at a local field office, where which office you are assigned to changes the answer by months.
I-485 — Application to Register Permanent Residence or Adjust Status
6.5 to 10.5 months
Burlington VT · Family-Based adjustment applications
Estimated median
5.1 months
The published range is the slow tail, not the middle: USCIS's low figure is where about 80% of cases have finished and the high figure about 93%. So half of cases finish sooner than 5.1 months — three in four by 6.3, nine in ten by 10.1. An estimate from those two published anchors, not a figure USCIS publishes.
