Hi there, the official status on USCIS is Response To USCIS' Request For Evidence Was Received. This was received on 6/25.
Interestingly, the status for I-131 has changed to "Your case is taking longer than expected to process. You will be notified if you need to take any action." since a couple of days ago. Would it be an indication that they are looking to approve the I-485 so the I-131 is no longer necessary?
From our letter for RFE, we were given the option to submit evidence either by mail or online. It also stated that we can reach out to USCIS if no response after 60 days.
