So I have 30 days to exchange my license?
That's correct.
Oh, I see what you mean. Then I'm going to tell it to him. In my case, what kind of license will I need or obtain? Could you please tell me?
IN your case, as you are going to be age 16, you would get a DJ-Junior Operator Class license. If you were over 18, then it would be a D-Operator Class.
