Applicants with Criminal Convictions
Do not forget to answer the criminal conviction question on your license application form. If this question is not answered, your application will not be processed and will be sent back.
If you have ever been convicted of a felony or misdemeanor (other than a minor traffic violation) or pleaded guilty or no contest (resulting in a deferred adjudication) to any in-state, out-of-state or federal criminal offense, you must provide a completed Criminal History Questionnaire (PDF) along with your application materials.
The department will conduct a criminal history background check on all persons who apply for a license. Criminal convictions are reviewed on a case-by-case basis. Licenses may be denied based on the nature of the conviction and how long prior to the application the conviction occurred. Depending on your criminal history, a review can take from one to six weeks to complete.
Individuals may request TDLR review their criminal background before actually applying for a license. TDLR uses the same process for this pre-application evaluation as the process described below. See the Criminal History Evaluation Letter page for more information.
Please see the Guidelines for License Applicants with Criminal Convictions, which describe the process that TDLR uses to determine whether a criminal conviction renders an applicant an unsuitable candidate for the license, or whether a conviction warrants revocation or suspension of a license previously granted.
