I have 15 months waiting for my case And I have to wait 5 months more
You can go to uscis.com. Scroll down to processing times click on that then put in your i-130 petition in the drop-down box then click on Potomac in the drop-down box. There you'll see what date they are working with. Like for me my wife and kids we got our ioe in December 2019. Now they're currently working on cases from July 19th. Honestly this whole process can take a year or two.
