AOS interview next week, mother in India on AP
I am a US citizen, had applied for my parents GC in October 2009. Mom underwent fingerprinting three times here, but did not get her AOS done in time. End of last year my father (who got his EAD and AOS smoothly) had emergency heary bypass here, and then they had to leave back for India for more tests. Mom left on AP. Subsequently I wrote a letter to NBC, MO to ask them to expedite my mothers case. Yesterday I received a letter stating that she has go to Philadelphia USCIS office next week for "Completion of application to register for Perm residence." Mom is in India now.
You need to contact USCIS customer service for guidance. Definitely put something down in writing that you are requesting a rescheduling. Maybe asking your Congressman's assistance is the best way to go for rescheduling.
Rajiv and his team has been handling Green card and related applications for me and my family since 2003. My experience has been excellent, to say the least. The long and not yet completed EB-3 India journey has been painful but Rajiv and his team have been great pillars of support all through. Our series of EAD and AP applications have been promptly worked on and many questions/doubts have been answered/attended swiftly. I especially thank Rajiv for a recent no charge conference call to discuss a new development with my employer. May God bless this team with greater success.
