I submitted 4 Service Requests, spoke at least twice with a tier 2 representative to inquire about my status. I also submitted an Ombudsman Request, once 105 days had passed. I know they reached out to USCIS on my behalf. I reached out to NIL, but I am uncertain they flagged my case, as after answering some questions, they did not get back to me. I also emailed the Nebraska service center, twice.
