I found lots of answers for my questions in this forum. But I still have questions I couldn't find a good answers. I will be appreciated if anybody can help.

I have been living in USA more than 3 year in F-1 Status. I have started working with my CPT since Dec 2008 and after graduation it was changed as OPT on May 2009. My company have filed my H-1B on September 2009 and it will valid on Feb 2010. I live and work at the same state. I am exempted from SS and Medicare for 2009. I am resident of the same state whole year.

-My brother lives with me and I sponsor his living and education expenses. Can I change my status from single to head of household and file him as my dependent and show his expenses in my deductions for reimbursement?

-I was a part-time student in Spring 2009. Can I claim these expenses in my deductions?

-Will I be eligible to file my tax return as a resident alien in whole year of 2010 since my visa status will be change on Feb 2010.

-I sold out some of my books on web. (Less than $200.00) I made some donations to some charities. How can I handle these?

-I have medical expenses in 2009. Not exceeding $3000. And I have some business related expenses.(Travel, training, buying tools/stuff for job) Should file these in my deductions?

-Is there any software/organization which can file foreign nations tax return properly without any problem? Can I get a name?

-I bought car in 2009 and I can show sales tax and registration fee in my deductions (State:CT).

-Am I going to file my state income tax as a resident?

If you are not married, you will file non-resident tax return. Nonresidents (except from Canada, Mexico & South Korea) can not claim a dependent.

To answer the rest of your questions:

For 2010, you will be dual-status UNLESS you marry in 2010. As dual-status, you CANNOT file Head of Household nor claim your brother as a dependent.

You prbably did not sell the books at a profit, and even if you did, the amount is so small as to make NON-REPORTABLE.

You can claim charitable deductions on your dual-status return.

The medical expenses may also be deductible; it depends if they exceed 7.5% of your aggregate income.

The business expenses can also be claimed as an itemized deduction if they exceed 2% of your aggregate income.

Cannot help you on your foreign tax return. Email me at [email protected] if you need help filing your U.S. non-resident alien (NRA) return.

Sorry, but the sales taxes and registration for the car is NOT deductible on a NRA return.

You CAN file as a resident in your state if you wish, but, legally, you can also file as a non-resident due to your student status.

Thank you very much both of you!
