Questions about selling on other Amazon site, please help!


Hi everyone, we had been sold on the for over 4 years, now we want to sell on JP and SG site. My question is do we need to provide different email address for register on those sites? What information need to be the same as US account and what information need to be different?
And if our JP and SG accounts unfortunately deactivated at once for varification after we register, will our US account be affected? We are affraid it will affect our US account and it will be deactived too.
And any advice on register on other sites? Thanks very much for your answers.
