Each country operates diffently on credit histories.Ur credit history will never leave US. U will have to buid up a new one there.
Make sure to maintain a good credit history here in the US cos a bad history may show up anywhere in the world and wud be linked to the passport number so any immigration authority may be able to track based on passports.All I want to say is once cannot commit major financial crimes and leave the country.
