12月17日公民试完成，1月9号系统状态更新为：
Oath Ceremony Will Be Scheduled
We placed you in line for your oath ceremony and will send you a notice for Receipt Number NBC*xxxxxxx with the date, time, and location of your oath ceremony. You should receive your notice within 30 days of its mailing date. Please follow the instructions in the notice. If you move, go to www.uscis.gov/addresschangeto give us your new mailing address.
但到今天，我还没收到通知信。请教8老师，不知道这正常吗?
-Yes, it is normal. You can call USCIS if you worry too much.
