I'm Planning To Join FIDE
Basically all u have to do is play in otb events that are fide rated. U don't really have to "join". It automatically happens IF (a big if) u have a performance rating over 1400 in the fide rating system which is a bit lower than uscf.
And u have to play a minimum # of games for them to list u.
Hello friend. My only advice is to look into other organizations. FIDE is a good one and ofc recognized by the chess world, but there are other legit and positives orgs.
I encourage anyone that is serious about the game to establish an OTBR. As I understand it, the ratings/game here is subjective.
Other than that...good luck!
