I would think so, probably yes. But don't quote me on that.
Can a non US-citizen get the NM title by achieving 2200 USCF?

I am currently studying in the USA and was wondering if I play in tourneys there, whether or not I can get the national master title if I am able to achieve 2200 USCF. I have tried finding answers, but have been unable to do so.
Also, is the rating system and initial rating system the same for FIDE and USCF?
Yes, any US Chess member that gets a 2200+ OTB rating after their 26th game is awarded the NM title.
US Chess uses a rating system developed for them by Mark Glickman and the rating document can be found on his site. It's not the same as the FIDE system.

USCF is just trash. Don't even waste your time with that.
If someone is in the US and wants to play rated chess, then they'll need a US Chess membership.

The child is a foreginer and is in the US just for studying. He doesn´t need to worry about chess for now (he hasn´t even reached 2400 in chess.com). It´s more valuable for him now to focus in his studies. I´m sure he will have time to develop his skills when he is back in Norway. Also it could be pernicious for his play to be influenced for such a trash of a league.
