I am filing for my parent's Greencard while they are in the United States. I used the website https://egov.uscis.gov/processing-times/ to see how long does it take to go AOS route and it sounds like it takes more than a year for that. However, there is no authoritative uscis source that tells me how long does it take to finish
I found some sources like https://citizenpath.com/green-card-consular-processing/ which say that it takes 4-12 months to do consular processing but still this is not coming from USCIS.
My question is that is there a USCIS source that can tell me how long does it take for consular processing to finish?
