They have an internal guidance sheet that we have seen, and it does state the 15th.
That said, we still expect some inconsistencies both before and after that date. For example, some travelers may receive 30-day stamps early, while others may continue receiving 60-day stamps after the 15th.
Generally, it takes a week or two for changes like this to be applied consistently across all entry points.
Just make sure to check the stamp right after, and if you see any discrepancies let the officer know to confirm if it was intentional.
