Does Authorize.Net support international transactions? From authorize.net FAQ: http://developer.authorize.net/faqs/#7421 for source

Yes. Merchants can submit transactions to the payment gateway on behalf of non-U.S. customers. To do so, the merchant’s bank account must be with a financial institution located in the United States, and the merchant must be configured to accept the customer’s card type: Visa, MasterCard, American Express, Discover, JCB, Diner’s Club, or EnRoute. The payment gateway will submit the amount of the transaction to the customer’s card issuer, who will then handle all currency conversion to U.S. dollars. Since default Address Verification Service (AVS) settings may cause foreign transactions to be declined, merchants who plan to regularly accept international transactions should make sure that their AVS settings are configured to meet their business needs.
