If you wish to have your PokerStars account updated from a US address to a non-US address, PokerStars requires you to prove that you are resident outside the United States of America (or territories of the United States of America).
You can email email@example.com
for the specific information that we require for your account. This will vary in different countries, jurisdictions, and will depend on what data we already have on record for you.
