casestatusext .com has a pretty cool tool for checking other people’s case numbers and comparing them to yours. So you can see what dates are being approved and compare it to your receipt number. For example, my date of receipt was March 7th, and using the tool I can see that these past days they have been processing people with dates near to mine (3/6, 3/7, 3/8 etc). I even saw a person who submitted 2/26 for 129F and was just approved on the 11th of this month (WAC so California service center). But other than that it’s a case by case process, hard to say 100% which dates they are processing currently.

uscis approval can take anywhere up to 14 months for some unfortunately
