I had plead guilty to misdemeanor possession of marijuana and served time and no probation in missouri in 2003. I am told that the conviction can not be expunged because I was not on probation but served time instead, the incident happened 2 days after my 18th birth day about 10 years ago, I had a public defender, I live in different state now and I am currently a registered Nurse, Graduated with lots of honors and research and great MCAT score in order to go to medical schools, this conviction is preventing me from pursuing my dream to be a physician. IS there any way or exception in any form that i can pursue for seal/expungement, even trying to appeal the case???? any attorney referrals? is there any new laws? English is my second language and I was not informed about the consequence of my guilty plea and also told misdemeanor is a simple charge. Please Help..
