HI I am new here. I wanted to post comment to this question. Even if you have had this expunsed or sealed it will show up in your BCI report. Do not hide your DUI. Just attach the letter they are more apt. to give you the license if you tell the truth. If you choose not to they state that can and will deny application. Also if they give you license and somehow you fall through a crack because you choose not to disclose this, you will have your license suspensed and pay multiple fines and maybe indefinately or revoded. Please just be honest and send the letter.
