I am in the same boat (for my in-laws) their oath is on Dec. 29, no email as yet. I just called this morning and he told me that I should follow up a week before the date or even couple of days before. He said, you will receive an email. He even said that the date maybe changed or its not final. I dont know what that means I think he saying it may be case by case or in case they find something so they may change the date.The instructions will be sent via email.
