It’s really hard to understand how this is supposed to work. “About a month” doesn’t seem accurate enough to be a real rule. Is 40 days ok? 20? And what if you’re traveling off island in the preceding month? It seems far-fetched even for these jokers to insist that people come TWICE in person for an extension, first to create an appointment, then for their application. I’m wondering if it’s more a “suggestion” than a rule? Can it be that they would refuse to extend a stay even if you go two weeks ahead of your expiry, with all the right paper, just because you hadn’t made this new extra visit, weeks before?
