Absolutely. I went online and figured out who my congressman was (this isn't something I used to keep up with, tbh). Under the contact us link I wrote an email explaining my case. Name, receipt numbers and email and phone number. After I sent it, i received an email saying they were going to review my email but if this was a time sensitive subject to contact his office directly. So I called and the secretary emailed me a Privacy Authorization Form. I had to print it out and fill it out and sign it. Within this form there's one full sheet that's for you to explain your situation and state what you would like done. I explained the issue. Talked abt the delays. Spoke abt my job and my expenses. Basically sell yourself. I spoke abt urgency. Provide my receipt numbers again. And emailed it back to the caseworker. That was on 12/19 in the afternoon. I called to be sure they received my email and she told me she would start an inquiry in my name. My case was approved on 12/21. On 12/21 I received a letter from my congressman stating the answer USCIS had given him. Mine said they were doing a background check this was dated for 12/20. So they got an answer the following day. It doesn't hurt to try. Best of luck.
