Family Based Greencard

My wife (USC) petitioned I130 for me last September. She is an army servicemen and from Oct 2018 to Apr 2019 she was in boot camp. I live in NY while she lived in SC during her training. Our I130 interview was initially scheduled on Apr 3, but my wife was still in her boot camp and couldn’t make it. We went to NY USCIS field office on Apr 15 and had our I130 interview. Our attorney was also present. During the interview, the IO raised some questions regarding our rent and income, then asked a few questions regarding our job, birthday, how we met and who were at the wedding reception. Then he asked both me and my wife the yes/no questions on my I485. For one question he asked my wife if I had ever been arrested in the US. My wife told IO no because she didn’t know about it, but I was arrested for driving with suspended license. I explained this to the IO and showed him the case disposition from the court. At last, he gave us a paper saying that he doesn’t need more documents, but my case must be held for review. Now it’s been a month but my case status still shows Case Was Received and the last update was Sep 2018. I heard that most cases are approved within two weeks and if it’s taking longer, something is wrong. Should I contact a congressman to expedite the case?
