Is this FIDE only? 

This doesn't help me

Talk to me like im 5 then 

It says top 3 sections are FIDE rated at the bottom it says FIDE Rated: Yes so are all the other sections USCF Rated? 

I'm pretty sure most FIDE rated tournaments in America are also USCF rated. From what it advertises it looks like anything below U2000 is only USCF rated

#6 I asked the arbiter and yeah you are correct 

Yeah, the top 3 sections should be fide rated AND uscf rated.  Sections under that only get uscf rated.

Although it would make more sense to rate as many sections as possible because it would make the fide ratings more accurate all the way down.  It's ridiculous seeing 1100 fide ratings and uscf 2000 ratings for the same player.

It costs more money to rate each section and in order to even get a rating, players have to face a sufficient number of players with established ratings. It probably doesn't make much sense to do it for lower sections where most players won't even get a rating.

As time goes on there will me more players at lower levels that are FIDE rated.  One hurdle for FIDE rating is the license fee that FIDE charges for people to become NA, FA or IA.  The US Chess Fed does not charge any fee for people to become US Chess tournament directors (TDs - equivalent to arbiters) regardless of how high up the ladder a TD goes (the levels are Club, Local, Senior, Associate National and National).  A TD can request a test and have it graded with no additional fee.  To ensure that TDs are experienced before running FIDE rated sections a player has to be at least a Senior level TD before being allowed to take the NA test (no charge for the test since it is administered by the USCF, but if the TD passes then FIDE requires its licensing fee before the person can become an NA).

That limits the number of licensed arbiters available to run an event and makes staffing much more difficult if every section is FIDE rated.
