I was an intern at a company in 2016. I am currently on F1 visa (Non Resident Alien under 5 years) and therefore exempt fro SSN and Medicare taxes (FICA).
My employer withheld these taxes and gave me a W2 in January 2017.
They said they cannot issue a refund to me, nor give me a letter for Form 843. However they can give a corrected W2C moving all FICA taxes to Federal taxes.
Does this mean if I file my tax returns with new W2C then I will get my refund of FICA as it will count as excess Federal withheld?
There have been questions like these in the past but none of them addressed what happens if employer moves FICA to Federal.
