Should be valid worldwide, even though the format of the plate is unfamiliar, but before answering I have to say I have only flown IFR in Europe. Here pocedure turns are not very common - most procedures have an outbound track that is not resiprocal to the final approach.
It would not even cross my mind to do the procedure turn. The point of a procedure turn is to take an aircraft flying outbound and return it to the reciprocal course on the same path across the ground. If you fly the arc you are not outbound.
It is sometimes hard in training to see that the point of instrument approaches is not to trip up unwary students, it is to take an aircraft into a position to land. A procedure turn would not increase flight safety (the arc is flown at 2600' so no outbound descent is required, the only reason I could think this might be necessary), therefore I can only assume it would not be expected. The only result would be confusion and higher workload on the pilot, harming flight safety.
If they wanted you to fly the procedure turn then they would have arcs that lead you onto outbound legs, not onto the inbound.
