What is the statute of limitation for auto accident if the injured person lives in a foreign country?

Personal injury lawsuits have a two year statute of limitations.  The only exception is when the person later discovers they were injured (which normally doesn't apply to car accidents)--in which case an action can be brought up to a year after dicovery of the latent injury.

There are no special rules or extensions for people living overseas.

Best of luck and thanks for your service.
