How long is a removal proceeding going to take?

I am under removal proceedings since February 2013. In April 2013 I got married to a US citizen but after a couple months the Milwaukee sub office denied my wife's petition for the I-130 and they canceled our marriage because my wife was divorced only 2 months before we were married. We did not know the law of not being able to marry for 6 months after she received her final divorce agreement. So that’s why it was denied. Then we were married again in February 2014, we did procedure over again, however ten days ago we received a letter from immigration. My wife's petition is denied again. Now I don’t know what to do, I did not have any interview since I was placed under removal proceedings a year and a half ago. When my wife applied for petition I-130 second time, my lawyer told me that I do not need to go to court. She told us as soon as my petition, I-130 is approved and we pass the interview for the green card, my attorney would send the papers to court and cancel my case. I believed her and I thought she knew what she was doing, unfortunately I wasted almost two years and money. I have a few questions from your past cases: 1. Is it possible to complete this case? 2. What are the steps we need to take to finish this? 3. How long will this procedure take? I know that I have no choice and I need to wait, but I don’t want to waste the time and money by doing it wrong. Your advice would be appreciated. Thank you.
