I have received my FL notice today with today\'s appointment date due to mail delay. I called INS office to reschedule my appointment, they said you can not do that on the phone, follow the rules on the Notice Of Action to reschedule it. If I want to re schedule I have to send back NOA to the INS. On NOA it is clearly mentioned that "Re scheduling your appointment will delay your application. If you fail to appear as scheduled OR request re scheduling, your application will be considered as abandoned." Please suggest how I can proceed. Your input would highly appreciable.
