My wife and I filed a joint I-751 petition in April. At the end of May we received a letter from USCIS saying we will be receiving a letter for an interview date. On June 13, 2009 My wife broke down and told me that she committed a petty thief crime on September 12, 2007. She didn’t tell me about it because she was ashamed. She was convicted of a misdemeanor and sentenced to 3 days in jail. She told she was going out of town with a church group. Because I was unaware of her conviction when I filled out the I-751 petition in April 2009 I marked the box of “no convictions” for my wife. Two days later my wife informed me that I made a simple error on the I-751 petition and so she had filled out a new I-751 petition to fix the error. On June 13, 2009 she admitted to me I did not make an error. Because I did not know about her conviction and she changed the I-751 petition to indicate that she had been convicted of a crime. She admitted that she tricked me into signing the I-751 petition with the convicted of a crime box checked hoping that I would not notice the convicted of a crime box checked. I decided to file for divorce on June 18, 2009. Because I found out she is having an affair with another man for the last 2 months. On June 20, 2009 I received the letter for the interview date with USCIS for July 8, 2009. I called USCIS about withdrawing my I-751 petition and they said just turn in the interview letter with and explanation of the reasons why you are not going. I did that on June 22, 2009. Is this all I need to do to withdrawal my petition? What are my wife options now? Does she have to file a joint wavier I-751 petition? Will the conviction of a crime hurt her petition? Will she get deported? She is from Taiwan.
