Moved to Hong Kong earlier this year and there are some credit cards which offer bonuses which I am tempted to apply for. On the other hand I am worried this might mess up my US based credit report and especially my US based credit card company relationships. Since moving here I have been using my CSP and so far nobody asked me why I am racking up charges exclusively outside the US, thought by now they would have asked at least. I understand that transunion is here and is used for credit checks. While I do not have a long cedit history here I do have a long standing one from the US and am reluctant to jeopardize that.

Does anyone know the implications of getting a credit card here in HK and if it may compromise my us credit cards?
