Will a bad credit history in Canada follow you when you move to the US?

Only if the consumer voluntarily reveals the information or finds it necessary to reveal the information to obtain credit in the U.S. It is true that Equifax and TransUnion have bureaus in other countries. However, consumer credit information either good or bad cannot be transferred from one country to another due to the differences in consumer laws, such as the U.S. FCBA, FCPA and so forth. Yes, particularly from Canada, as they and the US share many of the same credit agencies. The best you can do is pay down balances and wait patiently for old accounts to drop off your credit history.
