What rules should you follow when interacting with a Filipino as a foreigner?

I want to make friends once I move to the Philippines to start my new life but I know customs and ways of interacting are likely far different than they are in the United States.

Let’s say I see a Filipino in public that I want to attempt to make friends with. What’s the best way to approach them and how do I properly interact with them? Are there any gestures I should be aware of? Do Filipino people kiss each other on the cheek to say hello like some other countries do, or are there perhaps other customs that I should be aware of. Are there taboo things that I could unknowingly do to accidentally offend a Filipino if I’m a foreigner? I’m in my mid 20s and my primary goal once relocate to the Philippines is to make friends and meet people so I won’t be lonely.
