it doesnot matter what kind of status are you in. if you have lived in us for more that 6 month/183 days in year 2010, you are considered as a resident for tax filling purpose. so do not be afraid to get all the benefits and deduction that you get as a resident. if you need futher information about the deduction or you need any infromation about your filling status read first few pages of publication 17.
