Play in FIDE tournaments and perform at the 1800+ level to get rated. Your "Live Chess" rating is only 1250, so you would need to be a bit stronger first. FIDE-rated events in the US tend to be the huge tournaments, like the World Open.
If you live and mostly plan to play in the United States, a USCF rating is probably more useful. Most local tournaments will be USCF rated. :)
Hey, I was wondering how do get an offical FIDE rating?
Thank you, KFC
