I'm also looking into the refund of SS and medicare for OPT.
Is the statement from employer for refund of medical and SS tax a must this
year? Since the instruction of
form 843 mentioned it. http://www.irs.gov/pub/irs-pdf/i843.pdf
And how to calculate the amount to be refunded? Is it the total value
withheld showed in the form w-2?
Thanks!
