Vera&John is regulated by Malta and powered by Microgaming casino games. Both Malta and Microgaming do not accept citizens from the United States of America.
I sent an email to the Vera&John support to get a clear explanation. Here is their answer :
Thank you for the email.
Due to the special circumstances the US has for online gaming; we do not accept US player, neither US citizens nor users that are physically in the US.
Thank you for your understanding,
Have a pleasant evening,
As part of the US gambling law, Vera&John preferred to step back from the US Markets. However, some online casinos still continue to accept US citizens. Check our top 3 US Casinos.
Technically, you could play to Vera&John if you signed up from abroad. For instance if you are in vacation in Colombia or in Argentina, you could play to Vera&John while you drink your Cuba Libre. However, you should not use a US address and an american credit card (from Bank of America for instance).
This is the same problem as "signing-up from abroad". You could use a VPN to play to Vera&John, but you would need to have a real address outside of the US (with electricity bill at your name for instance). If you have an aunt abroad, for instance in the Russia, it could work. Otherwise, in case you win a $7,000,000 jackpot, Vera&John could block your funds..
We know that Bovada is currently accepting US citizens. It is powered by Top Game software and offers a nice welcome bonus.
