The online information is not 100% accurate, please share your experiance

I have read in few places…

The online information is not 100% accurate. There are plenty of cases where the case status shows “Initial review” even after the person has received his/her approval notice

Did you heard or aware of such case if yes then what is the best way to find exact status ?

Yes, the information displayed is not real-time, and USCIS takes a few days to update the information on their site. In my case, my petition was approved on Jan 11, and the site was updated on Jan 14.
