What is Filipino-American? My father is Filipino and my mother is American. The child is a hybrid, but how can he be an American? And joined the Philippines!

Filipino Americans and Filipino Americans are two different concepts. Filipino-Americans refer to Americans with Filipino nationality, and Filipino-Americans refer to Filipinos with American nationality. Just like a hundred years ago, many China people immigrated to the United States, and they obtained American citizenship. They are called Chinese in the United States, and their descendants are called Chinese of China descent. We call these people Chinese Americans. So according to what you said, my father is Filipino and my mother is American. Of course, half of the child is American, but his nationality is the Philippines after his father.

(nationality can be understood as hukou, that is, where are you from)
