rajeshGC,
There are many cases where the FP2 has been sent only after 2 to 3 months after the 15 months expiry date.
And you will surely need a FP2 before you get approved. I will be very surprised if you get approved now without FP2.
So put all your energies to get FP2 soon.
Try contacting Senator, Apply AP and EAD renewals if possible. Do not leave any stones unturned.
Wish you all the best in receiving FP2.
