I go to Immigration Timelines above, and I don't even SEE the I-130 listed. We submitted the I-130 for my wife's sister (my wife is a naturalized citizen) June of 2021 and USCIS website says the processing time for 80% of applications is 49 months at the California Service Center, but as I read it can take 10-15 years to actually bring her sister here. What I am trying to figure out, is what is the step-by-step process after that and how long for each step can I expect? I posted my wife's timeline here listing every single step of the way but I cannot find a sample timeline for an I-130 for her to bring her sister. Can anyone point me to some sample timelines?
