Frankly, this is quite common.
It's more like a technical verification of the payment method you prefer for the withdrawal. Once you deposit, I recommend you to deposit a bit more to ensure you pass 3x deposit wagering, this specific method will be registered in the casino - meaning it will be approved for the withdrawal.
As I said, this is quite the usual procedure. Take it like this: If you started by deposit, you would skip this part.
No deposit bonuses or welcome bonuses for new players are eventually marked with a hint saying "deposit is mandatory to withdraw the funds"
To get more familiar with those procedures (verification, validation, AML), I recommend you to undergo these free courses:
