Hi LUPEN. I rarely give advice about Chinese since I'm a nOOb.
On Baidu, there's a question, "How to say in English 欢迎你来我家做客?" and the answer is "Welcome to my house."
(the two characters at the end 做客 zuò kè = to be a guest or visitor)
This is a nice photo that includes 欢迎你来我家 in its caption.
Maybe, it's a baby announcement, where the parents are welcoming the little girl into their house and family. I'm not sure.
