Your case is closed and post arrest you want to get your case sealed or expunged. Sealing and expungement; post arrest is very important especially in this economy where jobs are hard to find. Many people wonder what the difference between sealing and expungement[A1] is. First question is whether you are able to do either. You cannot have any convictions on your record and your case had to be either dismissed or you received a withhold of adjudication for a charge that qualifies to be sealed. There are some charges even if you have no criminal history and you received a withhold of adjudication you cannot seal or expunge them.
The job market is hard enough to get into nowadays, even if you have a clean record. So put yourself in the shoes of someone who has a criminal record.
