Country of origin has no relation to payout delays, other than users who have entered tax information for their account that has resulted in an incorrect withholding rate (not hugely common, but it does happen).
A common thread for just about every user in this thread who have replied is outdated tax information that we were unfortunately unable to reach out to about the issue before the payouts became delinquent. This is an issue that has affected many users at the start of the year, enough that it's been challenging to contact every user who has the issue until it shows up in the payout backend or until we are notified of the issue by a support ticket or a moderator.
We sincerely apologize for the inconvenience that this has caused, and we apologize that we haven't had the opportunity to make a larger statement on the issue, but please rest assured that we are constantly working to address these issues and get them sorted for everyone. Thanks again for your patience.
