CP and marriage combined..
I agree mumbai seems to be handling better than chennai in these cases.
Got married 12days before my interview and submitted spouse pkt 3 on the date of my interview. Called chennai to check if they can issue an appointment for my spouse with me but they said she will be given at a later date. Submitted DS 230 part 1, marriage certificate copy, Birth certificate copy, my appointment letter, my I-140 approval copy and my notorized employment letter copy.
Waiting for spouse interview to be scheduled soon.
