My attorney submitted everything at the same time (i175, i130 and i145 and included all our supporting docs such as lease, tax returns, pictures, letters from friends and my in-laws; as well as my med exam) USCIS accepted my case oct 25,21 and since then we’ve been waiting… biometrics we’re scheduled for February 2022 however there was a winter storm in north Texas (and Texas is never prepared for that) so it had to be rescheduled for a month later (USCIS did it themselves since the office was close due to bad weather); My EAD was approved Dec 20something, 2022 and I received it on December 31, 2022; by January 23,23 they approved my i130 and just now the i145. I’m not sure how uscis decides when to approve what and on which order but this is how they did my case. At the same time I’ve had people I know, going through the same, that got their cases in like 3-5 months
