Apostille Query

Hi everyone, I’m new in legal practice and I just want to clarify something based on your experience.

If a document is executed in the US and will be used in the Philippines, does it need to be apostilled first before notarization, or is it already sufficient if it is notarized and sworn before the Philippine Embassy/Consulate?

For example, if the document is notarized at the Philippine Embassy in the US, is Apostille still required for it to be valid in the Philippines? (What i know na hndi na po sya kailangan ipa apostille, but i wanna be sure if tama po ba tlga. My clients are in US)

Sorry if this sounds basic, I’m still new and would really appreciate your insights. Thank you so much!
