This is a scam company
This is a scam company. They claim to issue an international driver's license, and will happily take your money for this purpose, but the document they issue is not valid and will not be recognized internationally, potentially costing you huge fines and headaches. There are only two valid issuers of International Drivers Permits in the US (AAA and AATA), and they are a fraction of the cost of the fake ones issued by "International Driving Authority".
