So, after approval on 13 Jul, my lawyer sent an email on 14 Sep, then I sent a public inquiry form on 24 Sep, again chatted with USCIS live agent on 1 Oct 22, who told me that I must contact again after 90 days of approval ie 13 Oct. So my plan is to contact live agent through Emma on 14 Oct and then file for ombudsman on 24 Nov (60 days after public inquiry)....
