我米有给我妈写邀请信，用英语给签证官写了一封邀请我妈来的信。不过我妈被据了。不知道对你有没有帮助。

I don't think it is quite necessary to write a invitation letter to
your Mom. You may write a letter to visa officer to explain why you
want to invite your mom to U.S and brief introduction of your
background.

write both bah. a chinese one to ur mom and an English one to visa officer

是的，是的，宁多不少啊

给我妈的信要不要翻译成英文呢?给签证官的信已经有了.对大家的帮助感激不尽......

我准备了给签证官的信(英文)，给父母的邀请信(中文和英文)，其实都没看，但准备了总没错。材料准备得越充分越好，用不着是另外回事，万一要是因为少准备了材料被据多亏阿

说的完全正确
