Where are North American Android 6 ROMs?? Galaxy Note 5

[spacemanjupiter]

I have a Galaxy Note 5 that has been giving me nothing but problems since I got it. I have it rooted with custom firmware 5.1.1 but I'd like to get 6 on here. I see plenty of articles about flashing Marshmallow on here but I can never find a ROM that isn't India, South America, Mexico or some other country. I have no idea which one to download for a US device. I don't know which 3 letter region code to look for either. Any advice would be appreciated. I have an SM-N920G from Tmobile.
