Hi Miguelzo. I can't advise on what you should do. My wife had to do a waiver but it was only for prior illegal presence, not misinterpretation. I do think it's pretty complicated. If you haven't already, I would check www.immigrate2us.net as they focus more on waivers than visas. Also, I would call around to 2 - 3 lawyers, you can find several who will do a free consultation on that same website I mentioned.
My wife's case was difficult and complicated. We were faced with the same dilemna of if I should just go to Mexico or try the waiver. After a lot of research, we decided to try the waiver and it worked out (but we were denied once), so we had to do two waivers actually. I would just get as much information as you can before you decide what to do. Good luck.
