回复：别客气。另外希望我前面的话没有得罪你。——回复：多谢Bodd！

Thanks to Bodd. But I wrote the invitation letter. I heard that the invitation letter has the legal effect that I will be responsible for all of the things that my niece does in the U.S.
Is that so? So in the legal aspect, I am the person who is responsible for my niece.
