It depends on the specific laws of your state. In California for instance, the ability to remove the conviction from your record depends if you spent time in state prison or not. In Texas, your only option in most cases will be a pardon from the Governor. I used recordgone.com to clear my record in New Jersey. I highly recommend you consult with an attorney registered to practice law in your state to see if you meet your states eligibility requirements for criminal record clearing.
