Newly married to foreign national

This is the first tax year I have been married. We were married overseas. My wife is a foreign national and has still not gained entry to the US yet (immigration visa pending). I have a daughter with my wife. My infant daughter is a US citizen and has a US passport.  Neither has a social security number or ITIN.

 

Would I maximize my return by filing jointly?

Do I need to report my wife's income?

If I do not file jointly, am I able to claim my wife as a dependent?

Am I able to claim my daughter as a dependent without a social security number?
