When a casino unnecessarily asks for documents it means they're looking for a way to keep holding your money for their purposes, and $1200 is still a very small amount of withdrawal that even a level one verification should approve on many casinos.
Being unnecessary though with KYC is another clear sign of a scam attempt and for sure you should look out for any of such casinos.
