I was doing OPT as a part-time from June 1st, 2007 to May 31st, 2008.
With my condition, I didn't realize I didn't need to pay both Social Security Tax and medicare.
This April, 2008, I did my tax-return for a half year (June 1st to December 31st, 2007)
Is it possible for me to get the money back for entire year now?
Thank you for your kind advice!
