Still no receipt notice for I-765

Filed 485, 130, and 765 concurrently through our lawyer back in February. We received receipt notices for the 485 and 130 back in late March.

We have yet to receive a 765 notice. Our lawyer put in an inquiry but hasn’t heard back yet. It’s particularly frustrating since my husbands OPT will expire at the end of the month. Any others experiencing this?
