AOS application related question


Registered Users (C)
Hi my I140 is approved, PD is June 2002 EB3 India. My questions are

1) Is it advisable now to apply for consular processing?
2) Do I need company/lawyers help to file for consular processing?
3) Say next year if my PD is current then do I have to immediately go to US consulate to get my GC? if not how much time it takes from the day PD is current and actual interview at the US consulate?

Thank you for answering my questions
