Try a place that does not assess a background check. Look under local/private listings. Try not to be a felon in the future.
The short answer is yes. The more detailed answer is, a felon cannot have access to or control over a firearm. Simply being in the vicinity of a firearm does not necessarily mean that the person has access to or control over the firearm. However, generally speaking, having a gun in a house where there is a felon is not a good idea. If you have a CCW but no gun in the residence, there is no problem.
The separated spouse of a convicted felon is not legally prohibited from purchasing a firearm. HOWEVER, if it is contemplated that the convicted felon may be anywhere around the firearm, ESPECIALLY IF THEY ARE IN THE SAME RESIDENCE, it will place the convicted felon in "concurrent possession" of that firearm and he may be arrested, charged, and imprisoned. ALSO: If the evidence suggests, the prosecution MAY try to prove that the separated spouse knowingly conspired to supply the availability of the firearm to the felon, and charge them as an accessory.
No, a felon cannot become a private investigator in Oregon even 15 years after the felony conviction. A private investigator must have a clean record without any felony convictions.
Whatever other rules they may have to comply with while on parole, the MOST IMPORTANT ONE IS there cannot be ANY firearms in the residence, regardless of who owns them. A felon living in a residence in which there are firearms is ruled to be "in "possession" of the firearm by virtue of his ready accessibility to it.
