My husband (from Canada) has been here for about a year now in the states. USCIS did a RFE on the I-485 because they needed his birth certificate. We have an attorney and he’s been wonderful on helping us. He said the RFE response has been filed on and that was on December 28, 2023. I looked online at our case status and it says that they received my response on January 4, 2024 and began working on it. It’s now March 5, 2024 and we have yet to hear back from USCIS on form I-485. It worries me that it’s taking this long. Most people say they hear back within 60 days or less but it’s now been 2 months.
