Hello. Starting sometime in January 2013 you will be able to change your Xbox LIVE Region directly from the Xbox web site.
Xbox Support is currently unable to manually change your Xbox LIVE Region in anticipation of this rollover to allow Xbox users to change their own Xbox LIVE Region. You will be able to change your Xbox LIVE Region once every three months once this function
has been enabled.
Stay tuned to the various Xbox blogs for when this functionality is implemented.
Did this solve your problem?
Sorry this didn't help.
Great! Thanks for marking this as the answer.
How satisfied are you with this reply?
Thanks for your feedback, it helps us improve the site.
