My US INS interview and Oath Ceremony is scheduled on Aug 9th, but I've booked my trip to China on Aug 8th, and I tried to change my trip schedule, but there is no seats available until a week later. I called CIS and asked if I can change my interview schedule, she told me that I can send in letter and request to change schedule, she also told me that it may be OK to change but will definitely delay the process. I don't know if anyone here had the experience of changing interview schedule, should I change the interview scheule or trip schedule?
Thanks in advance for your help!
