XiaoBaiTu, Pls help on reschdule date for Biometrics! mom20072007-03-19 06:19:12

Dear Xiaobaitu annd experts,

I received the notice of biometrics for my I-485 on April 11 but I am expecting now and my due date is around April 14. It is very psossible that I may not be able to go to do the bimotrics. My questions are:

1) Can I re-schedule my time to sometime earlier? If yes, what should I do? Call the 1-800 number directly or send the notice back asking for a reshcedule?

2) If I can not make it earlier, I heard if I reschedule the time, it will be usslay in 2-3 months late. Is this true?

Thanks,
