A criminal record can affect your job opportunities, housing options and even educational assistance. Unless you are able to expunge or erase it, a criminal conviction will stay on your record forever.
Everyone that has been arrested or convicted of a crime has a criminal record. Criminal records are generally kept by the state law enforcement agency in each state. State laws vary regarding who may access your criminal record but, in most states, a potential employer or landlord and most government agencies have access.
A criminal conviction, whether it is a misdemeanour or felony, will stay on your criminal record forever in most cases. Unlike negative credit entries or traffic tickets, the record of a conviction does not "fall off" your record after a predetermined period of time.
In many states, a criminal conviction can be expunged or sealed under certain circumstances. If a record is sealed it will not be available to the public. If a record is expunged it is destroyed completely. State law determines which convictions, if any, may be expunged or sealed.
