So I have asked this question a few times in the past and basically been told only executive action can remedy this (Governor Clemency).  I have a conviction of Assault II in Marion County, OR. from January of 2000 that I would like to have removed for work reasons.  I am an Apprentice Electrician that has opportunities to work for various clients that request a “clean” record for security reasons.  I have been refused access to certain jobsites in the past due to this criminal record which has hurt me professionally.  I have no offenses since that date and have had no interactions with law enforcement other than a couple of moving violations since.  I would hope that 16 years later I could be declared a safe and sane member of society, but apparently not to some.  
This offense was commited when I was 17 and I plead guilty to Assault II under Measure 11.  I have long since served my full sentence (70 months), paid court restitution, and still continue to pay Victims assistance for a huge, undocumented bill that they say I owe.  I have done EVERYTHING right since that point.  I am not looking to get out of paying anything, I just want to be listed as a non-criminal for professional reasons.  
Is this possible through legal action, or do I need a prayer and a pardon from the current Governor of the state?
