I was working as an intern with F1 visa status at a company but that company's HR didn't know that I shouldn't be charged for medicare & SSN tax, so they put me in that tax status and now I have graduated though in F1-OPT and employed in new company. But since I was put in that tax status the IRS kept collecting the SSN & Medicare taxes from me.
So how do I tell IRS that I shouldn't have been charged for it and get my money back?
Thanks a ton!
