That's the only number shown on their website. I don't know any other number.Thank you buddy!
I tried calling them every day but could not reach them!!!
I have this phone number : 18882422100
I don't know if you have another one?
Try calling them during and after lunchtime. Usually the waiting time is extremely long in the morning.
And don't let this affect you too much. It might take you more time than average to get the AOR, but what really counts is how fast your local office will process the applications, and that will make a much bigger difference in the long run.
