联邦税不可以抵，州税可以的，用1040, schedule A。但是如果你没有房子贷款的利息和房地产税什么的，一般来说你的itemized的钱数不会大于standard，就不要折腾了。

I found the info for resident alien claming treaty

http://www.irs.gov/businesses/small/international/article/0,,id=106254,00.html

Example: Article 20 of the U.S.-China income tax treaty allows an exemption from tax for scholarship income received by a Chinese student temporarily present in the United States. Under the Internal Revenue Code, a student may become a resident alien for tax purposes if his or her stay in the United States exceeds 5 calendar years. However, the treaty allows the provisions of Article 20 to continue to apply even after the Chinese student becomes a resident alien of the United States.
