All Revenue Giants bingo properties accept players from the USA (Bingo Hall, South Beach Bingo, Vic’s Bingo, Bingo for Money).
World Bingo Network (Desperate Housewives Bingo, USA Bingo, Bingo Workz) also accept USA players.
Bingo Mania also accepts us players.
I know that Bingo Gala, Bingo Mega etc (members of Bingo Entertainment network) are able to get US players.
Saturn Bingo, Bingo Heart, and Bingoroom also accept players from the us.
There could be more, these popped to my mind first 
Hope this helps
