Does it make any difference to apply for an apple membership developer with a U.S.A credit card & U.S.A contact address or with some other country credit card & address (let's say China)? Is it of more opportunity for the app created by the U.S.A registered developer to be featured in the U.S.A appstore?
no it doesnt matter where you got your account.. or rather... it shouldnt :D
Only some folks at apple could tell you and as Kabira said: "no one reveals trade secrets."
