Japan to USA but departing in Philippine airport

I am a Japanese Citizen and would be traveling in the United States, but I would like to depart in a Philippine airport, is it okay?

For these questions, you should directly ask your immigration officers for a concrete answer since this is out of our reach.

Hello Anthony, may I ask you why are you going to the United States because I am also from another country and want to continue my study in the US so is this a good idea or not my friend suggested me to join an online course from any online academy and get Bottom Up Skills recognition which is better than study abroad, is that right?
