Travelling with I-751 pending
 

Can any one provide information about travelling while having I-751 being processed

1) Can one call the service center from the UK to find out the status including interview date in case one is required

2) How much notice is given by the INS if an interview is required, in case one is travelling and needs a few days to get back

3) In case one cannot make the interview, what is the process to reschedule

4)Who schedules the interviews the service center or the local office

Any experiences / advice would be much appreciated

Cheers
