<p>Well, I just tried to file the TurboTax as Swimcatsmom suggested. Probably it’s my ignorance that I did not see any statement about whether I should file or not. However, I found out on that site that if I can be claimed by a taxpayer on their tax return, I only must file the tax return if my income is over $5800, which my income can’t ever get to. So I think I do not have to file. I will go to see the personel service at my school to confirm this. Thanks all. If you guys have any more opinion or suggestion, please post.</p>
