Want to go for AOS


Registered Users (C)
I had checked for CP when I filed for I-140. Now I want to go for AOS (I am still waiting for I-140 approval though).

1) What is that I need to do?
2) And does going for AOS means that the case will have to be transfered back to the Service Center from NVC? or can I stop the case being sent to NVC at all after SC approves I-140?

Please help,

Thank you for your time.
