本人去年2011.6 OPT 到 2011.10.1转成 H1B 老婆H4 已经申请了延期, 选择first year choice, filing jointly as resident. 现在不知道是否能用us-china treaty 20(c)的5000刀? 是否在8833表说明1月到6月是 F1身份,所以可以使用treaty. 打算这么说明行不行?但是转了H1B和用resident报税不知道有没有限制? Article 20(c) of the USA-China income tax treaty allows an annual $5000 exclusion of student wages from gross he article contains no time limit, and a Chinese student who qualifies for it may use the article for as long s he is a student in valid F-1 status, including during that period in which he is engaged in OPT in valid F-1 status. 谢谢各位。
