Credit history usually stays within one country. Even within the same credit card network or within the same multinational credit bureau, information is not shared between different countries. For example, Equifax Canada does not share credit information with Equifax in the United States. If a person has been living in Canada for many years and then moves to USA, when they apply for credit in the U.S., they may not be approved because of a lack of U.S. credit history, even if they had an excellent credit rating in their home country.
