Same BH solution for sites requiring 'US' writers, is to create a good stealth US Paypal account, complete with faux ID data/docs. Then use that pseudonym profile info on your "US" writing account as your "matching data."
To minimize complications you can plan to only earn $500 or so per site account (to stay under the $600 limit, at which point businesses feel compelled, rightly or wrongly, to send out paperwork like 1099s). Then end the account and start another faux PP and writing account, rinse and repeat.
