Is it this forum's opinion that USCIS prefers Interviews / Oaths etc. aren't rescheduled by an applicant? I ask because I have been eligible to file my N400 since 5/17/04, but have been holding off due to the fact I am planning a trip abroad mid Dec thru early Jan. My DO is San Francisco and current timelines look to be between 4-6 months roughly. Do anyone have any input regarding this matter?
