Steven, so sorry about the delay. It has been crazy today. You should NOT be afraid to apply. There is no criminal penalty and all that can happen is simply that they say no. While there is no immigrant waiver available to you for such a crime, there is a non-immigrant waiver available to you if you just want to visit. Apply now and get it out of the way and if you fail, apply again. There is no penalty.
First, you would have to file for a B-2 visa which can be found here:
http://travel.state.gov/visa/temp/types/types_1262.html
And you would need a 212(d)(3) waiver which can either be done by the immigration officer at the interview or after just on their computer (take a look at this link):
http://www.state.gov/documents/organization/87150.pdf
or on form I-192 which can be found at www.uscis.gov/forms. You can find more information here:

Now that I have given you an answer, you may rate me positively OR ask for additional information. Please do not rate me negatively for bad news or things that you may already know. That doesn’t help you or me. I am here to help you and I am on your side. Give me a chance to help you. All you have to do is respond asking for additional information. You are NOT charged per question nor are you charged per response. If this seems a little complicated or overwhelming, I can also offer you an additional service for a small fee where we can speak in private over the phone or through email that may be helpful (this is a public forum where anyone can read the responses). Feel free to decline it, but if you do, please remember that I am not given a salary, so the only way that I am compensated is if you rate me positively. So at least please use the smiley faces and a bonus is always appreciated if you feel I earned it. Also, your question does NOT close just because it says, “To finish…” I can still answer additional questions for you without additional charge. If I do not hear from you, I will automatically send that additional offer request. Thank you for your understanding and if you would like to request me in the future, just type: FOR GUILLERMO in the subject line and message box.
