I am a F1 Visa holder and I am about to join to the US IT Industry to do my Curriculam Practical Trainnng session which is a part of my MSC programm. The range of salary that I will recive is around 60000USD per year. I would like to know which percentage do I have to pay as the taxes per year and wherther it will be refunded back to me when I go back to my country after completing my MSC programm.

If you have not completed 5-years on F1/CPT, then your income is not subject to FICA taxes. So makes sure that your employer does not withhold Social Security and Medicare taxes.
You will file nonresident tax return. You will get personal exemption and deductions as per tax treaty. You must pay federal income tax and state income tax, which you will not get back. For nonresident tax filing, read: Your U.S. Tax Return: U.S. Tax Filing Requirements for Non-Residents (http://taxipay.blogspot.com/2008/03/us-tax-filing-requirements-for-non.html)
