Procedure
I operate PIC on a C560 under an FAA single pilot exemption. Training occurred [last year]; and I was signed off and given the schools FAA Exemption letter. Unbeknown to me; the Exemption letter under which I operate; had been changed by the FAA; and sent to my training provider; not to me.  My training provider failed to notify me of this change and as a result of this lack of awareness; I inadvertently operated single pilot into a foreign country. The foreign country authority advised me of the transgression; but said they would not register a complaint. As soon as I became aware of this; I did not operate single pilot outside the United States; as stated in the new FAA exemption letter.In my view; there was nothing unsafe which occurred; and I was simply operating as previous; however; the process by which this occurred; left me holding the bag. In my view there should have been a chain of people notified of this change; not just the training provider. This could have been a serious issue had an accident or incident occurred.
Cessna V pilot reported that he flew as a single pilot into a foreign country where his exemption letter was not valid.
