I filed a form 843 for the overpayment of FICA taxes in 2013. This was as a result of working for two different employers that had the same reporting agent. The common reporting agent appears on both my W-2's and I have aletter from them explaining and confirming the over payment. How long do I have to wait for a refund? I am a US Citizen and the only information I can find is with respect to international folks, not US Citizens.
