回复：急问：有无赴美保姆签证？

我是美国公民，我老婆是绿卡，将于3个月后生产。我们欲邀请我老婆的一个朋友（在月子医院做护工，专门伺候月子，女，45岁左右）赴美照顾baby。

急问：有无赴美保姆签证？

-No.

如果没有，请问可申请什么签证来美?

-B2.

我们需要提供什么文件?

-Invitation letter and I-134, but you can not use the reason that this person will come to US as 保姆 or working. Also it may be difficult for her to get the b2 visa, but just try whether she is lucky.
