I assume that this is the first time you undergo verification on a casino because once a casino asked you for KYC and freezes your account, you can't make a withdrawal that's automatic, unfortunately, like all the others are saying here there is no specific date the longest I encounter was a whole month, you mentioned it's only a small amount and you're ok with it, it's good that you're ok with it, others have a huge amount on their account and they have to wait indefinitely for an update on their account status before they can withdraw their earnings.
