Actually, this is not accurate.

All felony convictions will remain on the NCIC file for the remainder of your life unless you can get either a pardon or an expungement.

Pardons are granted by the Governor of the state and are usually difficult to impossible for the working person to obtain.

Expungements are very specific and I will give some basics for this to occur.

1. Expungement is state/crime specific. That means that each state has it's own rules over which felony crime can or cannot be expunged.

2. Time elements apply. Most states demand 5 years free and clear of all legal encumbrances. Some states demand 7 years.

3. Only a first time felony can be expunged. If you have two or more numbers, you are stuck with them for life.

4. The cost of the expungement is solely dependant on the attorney's fees and filing fees for the county you are dealing with.
