Most of the live blackjack provider has same license coverage and US always excluded to there operation. There is no casino here that allows US citizen to play directly unless you are using a VPN but still not legal. Try to search on reddit or your local online casino hub. US has a different license regulator so most of the live blackjack provider doesn't do much effort due to there limited market unlike Evo and Pragmatic which serves globally.

https://www.reddit.com/r/onlinegambling/comments/7ohyhp/places_to_play_online_blackjack/I don't mind using a VPN and submitting fake information (just address not documents like ID). I'm just worried about getting suspended and then not being able to get my money out if they ask for extra KYC.
I was using Stake.com successfully on 2 accounts, one of them had 50-60k wagered (1k profit before losing my last $340) before getting suspended (withdrawal only). When it asked for my ID, I would just submit an invalid picture and then deposits would unlock, then a day or 2 later, it would ask for ID, rinse and repeat for over a month. Not sure if they changed that policy because I got limited immediately when I tried it on a new account, and when I tried a blurry photo, I was able to deposit and bet my $25, but within a few minutes it's asking for ID again... Expecting my second ID submission to result in a suspension.
