i'm a us citizen,my daughter born in another country,how can i get or apply a us passport for my Daughter ?. she doesn't a us citizen..

U can't. You need to have a visa for her to enter USA. ( visa is not the same as passport.). Then u can change her status and apply for citizenship for her.

There are a lot of things to consider. It depends on the age of your daughter and she has to be in the U.S. legally (have a green card, be a permanent resident) to even apply. Most likely you will have to apply to find out what all you need to do.
