Many states have programs where you can expunge old convictions and start anew. Go down to the local chapter of "Legal Aid" ask about "expunging the record."
In some of the big cities there is a program just for this. Look for a "Self help center" at the courthouse that will have a lot of information. (it may be called something else too)
There are a series of forms you will need to fill out, along with he normal filing fees too. Most say you must have:
No crime of violence
Served your full time, including parole/probation, and then some, sometimes up to three times over.
Been a benefit to the public at large, employed, all that good citizenship things.
Show why this would benefit the people.
Then some convictions my be reduced to a misdemeanor and or expunged. Even if its reduced and still on your record, your quality of life will be better without the felony
Good job turning your life around. I wish you luck in doing so.
