Hello everybody,

I worked from March 2008 to September 2008 in my OPT and now in H1B visa. From the starting of my job, I am paying 25% tax and it same as my status changed to H1B. The 25% tax does not include SSN benefits and Medicare taxes. One of my friend said that while working in OPT the tax should be about 17% and later (when H1B starts) that will increase with addition of SSN benefits and Medicare taxes. But I paid 25% tax in my OPT period which even does not include SSN benefits and Medicare taxes. If anybody had similar situation before or has information about this issue, please share. I would also like to know how I can get refund of my extra cut. I will appreciate your answers. Thank you!
