Not A Lawyer. The fact is the law is clear. Convicted felons cannot possess a firearm. Clearance that you currently have is not that black and white when considering and their resources are more extensive. My suggestion, exsponge the felonies. You can go to the court house and apply for that on your own. No lawyer needed. A judge can review your case and records and can make the determination. From your information, I find this HIGHLY likely. Once this is done, your process that you are attempting to do becomes more likely as well. Currently, you are essentially asking them to bypass the current laws, make an exception which is against the law and greatly increases any possible of liability. Won't happen. Those lawyers just want to charge you money for doing this for you, then appealing your process.....which if they have any reason to really try (being they already have your money), they just gonna Rob you.
