From the instructions to the form: Acceptable forms of identification include driver’s license, military and military/dependent identification cards, passport, state issued identification card, cedular card (foreign), non-resident alien identification cards, or any other identification document or documents, which contain name and preferably address and a photograph and are normally acceptable by financial institutions as a means of identification when cashing checks for persons other than established customers.
If you believe driver's license means a driver's license from any country in any language, you are in. Personally, I do not think that's what they had in mind.
Alternatively, they have given you a rule of thumb; i.e., would you accept a non U.S. driver's license as ID for cashing an on-us check for a non customer? If you can say 'yes' with a straight face, you're good. Again, I would not. I encourage you to call FinCEN and get your final answer from them.
