It only changed from 30 to 60 days in July 2024. From what I recall, there were posts/discussion/etc for a few months about it before it was actually implemented
fair enough, but if immigration told him he needs a visa do they flag that in the system? I wouldnt risk it. Same happened to me awhile back, but luckily they let me through at the time and said next time you need a visa or you won't be let in again.
