I submitted the Application for A&A for my Dad the 23rd of October. I mailed it certified return receipt, tracked the delivery of the package on the Poastal Service website, and received the signed receipt back in the mail from the Post Office after it was delivered - so I know they got it. I was expecting to receive a letter acknowledging the application had been received and asking if I had futher information to supply. So far, I have not heard a peep from the VA. I sent the application to the regional VA center in Pittsburgh, where my Dad lives. It is my understanding that applications through Pittsburgh are forwarded to Philadelphia for processing. How long should I wait before follow-up, and who should I follow up with?
