Changing you Xbox region
Check if your region is in line with Microsoft's requirements. You are able to find the list of regions from the bottom of the following link: http://en.wikipedia.org/wiki/Xbox_Live
You are able to check your own region from the registration information of your Xbox account.
You are able to change the region by doing the following:
*Log in to your Xbox account on page www.xbox.com
*From there choose and press the button "My account" or "My account" - "Activity center"-"My profile"
*From the right side of the page you will find "Change Xbox account region". Proceed with the security check and change the region to a suitable one.
In addition to the previous steps you might also want to double check your billing information. "My account" - "Payment & billing" - "Billing info", then choose "Change billing address" and enter a valid address. If you are registering yourself in region you do not actually live in then a lot of people enter addresses for well known places, such as a local embassy.
You may also try the following:
• Go to https://live.xbox.com/AccountMigration.
• Log in with the account you would like to migrate to a different region.
• Click "Next".
• On the page "Moving your Xbox Live account" choose the region you would like to migrate your account to and click "Accept"

NB! Please note that you are only able to change your region once in every 3 months. This means that if you changed your region to a wrong region then you have to wait 3 months before you are able to change it again. If you do not wish to wait for 3 months then you may register a completely new account and register it in the correct region straight away.
