I did exactly on the 105 day mark but still haven't had any sort of reply. I also filed and OMBUDSMAN case and still no such luck. The furthest I have gotten with OMBUDSMAN is they told me they would contact an analyst to inquire the case but still no word. I guess its just wait and see. I also called USCIS again and request a 2nd tier officer, but literally all the officer did was read the processing dates off the website which we all know aren't accurate. Do you have any idea why its taking so long other than just bad luck?
