How long it takes for the I-485 to be approved, professional category in the EB3 process

Does anyone have any idea how long it takes for the I-485 to be approved, for the professional category in the EB3 process, after it has been submitted? I’m from Brazil, idk if this information is important.
Thank you!

There is no standard time for processing i-485.

It varies greatly with the specific service center where your application is pending.

Usually, it takes about 6 months to 12 months.
