I spoke to my facebook administrator and his response explains the non-us likes.
I am forwarding his response in this email and i hope that will clarify things for you.
This is what he emailed me:
I am sorry but for the bonus likes they are world wide. I have made sure that there are at least 1200 US likes so far...the customer will need to be patient. He will receive a total of 10,000 USA likes. plus bonus. - the bonus likes are world wide. If the customer does not want the bonus likes, I can cancel the administration. The USA likes are still being administered and the 10,000 USA likes will be completed in time. In total your customer will probably receive 12,000 likes...
I work hard for the likes to be administered. Please tell your customer to be patient.
I hope that answers your concerns.
Please respond to let me know if you'd like to continue receiving non-us bonus likes.
