Orders from customers in foreign countries are more likely to be fraudulent than orders from domestic customers. This is due to the difficulty of authenticating foreign citizens as well as the difficulty of cross-border legal enforcement against fraudulent activities.
The International AVS filter sets aside transactions from customers with cards issued in foreign countries so that you can evaluate them more fully.
