on finding title awarding OTB chess tournaments

So , only until relatively recently have i discovered the fact that some of the lower titles like FM can actually be won by winning certain Regional(?) championships. (although apparently they are establishing some min rating floor requirements to them as well, -200 from the expectation )
This seems to be an outside the U.S thing, and honestly im a bit confused how one finds fide rated events outside the U.S as is, So i will ask here. How do you find these title granting championships?

most of them that I know of are youth titles, or regional titles from australia, for example

Most of the chess tournaments you are talking about are primarily youth events. Since you appear to be U.S. based, I will give you a quick list of every event you can participate in to win titles. You can find this year's edition for each event with a quick google search.

These are events you are unable to participate in (age restrictions):

Pan-American Youth Chess Festival

North American Youth Chess Championships

North American Junior Chess Championship

Pan-American Junior Chess Championship

World Youth Chess Championships

World Senior Chess Championships

These are events you can participate in to potentially win titles:

Pan-American Amateur Chess Championships

World Amateur Chess Championships

Absolute Chess Championship of the Americas (extremely hard to win a title in this one)

Please let me know if you found this post helpful .

thank you for the superb answer!
