I am an F1 student <5 years in the USA and am eligible for FICA refunds.
I contacted my company and told them that I will be requesting the IRS for the FICA refund as I was very close to the last date for filing tax returns and there wasn't enough time. They accepted and I sent my returns to IRS. However, 6 weeks later, I received a check from my company with the refund amount and the corrected W2c document, even though I had asked them not to. Now that I have obtained the refund from the company, what should I do? Do I need to send an amendment to the IRS? Note- IRS has NOT sent me a FICA refund yet.
