My question is.. How to apply for dual citizenship if i already be an american citizen?
Best you contact the Philippine embassy or one of its consulates in the US. Normally your kid is a Philippine citizen by birth since you’re a Philippine citizen and you’re her mother, so chances are you can simply register her birth with the Philippine embassy to claim her right to citizenship. Be sure to mention that since she was born in the US, she’s an American citizen; check that that is not a problem in the case of the child of a Philippine citizen born in the US. As you might know, since 2003 the USA and the Philippines have a special agreement which permits Philippine citizens to retain their citizenship when they acquire US citizenship, whereas that would normally not be allowed if they became citizens of other countries. That’s how you could retain your Philippine citizenship. However I’m advising you contact the Philippine embassy precisely because your daughter’s case is different than your own.
