FICA Refund
If my employer deducted FICA tax but since I was on OPT I am not liable to pay FICA. Then I started new job. Later I asked my previous employer during tax filing regarding the refund. He gave me corrected W2 but by that time I already filed with taxes with my old W2 that had FICA deductions on it. I didn't receive FICA refund from employer but received the W2. Now employer is not responding to my questions about how I would receive my refund. Any thoughts on what I should be doing?
