My wife and I are L1 visa holders but our daughter is an L2 dependent. How do we claim her as a dependent?

My wife and I are L1 visa holders but our daughter is an L2 dependent. How do we claim her as a dependent without an SSN. My daughter doesn't have an SSN but my wife and I do. I appreciate there may be a need to get an ITIN for my daughter but is the dependency/deduction level the same with ITIN as it would be with a child who has an SSN?
