请教各位 这封套磁回信如何理解？

Thank you for expressing interest in my research, and to work with me on your PhD dissertation. You seem too have a strong record, for which I congratulate you.

As you may be aware, US government has imposed various types of restrictions on technology related matters when foreign nationals are involved. Some of my research has also been restricted in terms of who I can recruit.

I strongly recommend that you apply to our department, seeking fun ding support as TA. I will endorse your application. Once admitted and you start your work, I could try to request waiver for you to be able to work on certain projects.

Please let me know if you still plan to apply.

主要是第三段不太理解，为什么推荐先申请院系的TA。。。是这位教授不能保证给我提供funding的意思吗？
这样一来是不是存在即便我admitte，他也不能 request waiver for me to be able to work on certain projects的风险呢？

学术界的人说话都很直接的，不会拐弯抹角，就字面意思理解就好。大概意思就是我虽然有钱也招人，但是项目特殊不太好让国际学生参与。我觉得他能这么认真回复你，说明你还是很不错的。你可以顺杆爬问问他有没有推荐的同事之类的招人？试下也没坏处

也可能实话实说，有钱但是无法保证能fund certain国籍的学生。

就是字面意思啊，无法保证你能做他的project。你确实感兴趣的话，就先申请，来了再想办法让你进他的project

第二段说的很清楚 他手里有政府的项目 有些项目规定不能让外国人接触 那你不能做当然不能给你RA 因为RA的工资就是从项目的funding里面出 所以让你申TA 其实你也可以看看你们系里有没有合适的的fellowship
