遇到拿鸡毛当令箭的人怎么办？

我先生在美国一所大学找到个科研工作，于是我们全家2年前举家搬到美国。根据中美一个协议，他来美国头的3年免税。今年初，我们又顺利地拿到了绿卡。本来是一件很高兴的事，但是学校里一个人事处官员在我先生税务问题上百般刁难，让我们很生气。
事情是这样的：我们拿到绿卡后那个官员就说我们身份改变，无权再享受3年中美免税协议。但是我先生在网上查到这个免税协议对resident alien都是有效的。那个官员说我们拿到绿卡，不是resident alien（我们有居住权，又是外国人，当然是resident alien）。于是我先生在协议网站上收集了resident alien的定义给他。他没法在这个问题上做文章，于是改口说协议是针对那些来做科研或教学工作的人，既然我们有绿卡，我们就只是来工作和生活的，所以不符合协议要求(Due to you being a lawful permanent resident now, you are no longer here for the primary purpose of teaching, giving lectures, or conducting research, which is what Article 19 refers to. As an LPR, you are here to live and work, and are not eligible for the treaty.)。对于这种无赖我们改怎么办？

另外，我刚才没说清楚，对中国人, the treaty extends to resident alien.既然我们是中国人，这个免税协议对我们就适用。（我不认为我是什么无赖。我只是争取自己应得的东西而已）

Students, Apprentices, Trainees, Teachers, Professors, and Researchers Who Became Resident Aliens

Generally, you must be a nonresident alien student, apprentice, trainee, teacher, professor, or researcher in order to claim a tax treaty exemption for remittances from abroad for study and maintenance in the United States, for scholarship, fellowship, and research grants, and for wages or other personal service compensation. Once you become a resident alien, you generally can no longer claim a tax treaty exemption for this income.

However, if you entered the United States as a nonresident alien, but you are now a resident alien for U.S. tax purposes, the treaty exemption will continue to apply if the tax treaty's saving clause (explained later) provides an exception for it and you otherwise meet the requirements for the treaty exemption (including any time limit, explained later). This is true even if you are a nonresident alien electing to file a joint return as explained in chapter 1.

Some exceptions to the saving clause apply to all resident aliens (for example, under the U.S.-People's Republic of China treaty); others apply only to resident aliens who are not lawful permanent residents of the United States (green card holders).


我们的一个朋友和我们一样情况，他学校的人事处就没收他的税。他比我们幸运多了，没遇到鸡蛋里挑骨头的hr官员。
