Hi,
My brother just passed his N-400 citizenship intereview. He is a cashier in a gas station. few days after interview while he was in his job, the cop sent him a girl to buy a swisher. he forgot to check her ID. So, he was cited for providing tobaco to minor. he was given a traffice ticket with Infraction under section 308 (a). It is his first time and has a clean record, even no other traffice tickets. location is California. my question is: 1. Does this affect his oath ceremony? 2. Does this stay in his record and how long?
Thank you very much for your help in advance.
