Hi mate,
do you have funds that you are wishing to withdraw that are being held?
You may need to read the Terms of Service on Stake, because Stake have a UK version too :/
I have only ever had to provide KYC to Gamdom because I was trying to withdraw $14,000.
They accepted my UK driving license, etc. I explained I was from UK and they were fine with it. I received the full amount.
Worst case scenario is you might need to switch casinos and research it a little more.
Have a conversation with Stake and see if they will accept ID.
Find someone from Ireland to complete KYC on your behalf lol.
Good luck!
even if you send ID they will refuse you, good thing about it they let you withdraw, just move to Gamdom casino they never ask you for KYC
