unfortunately it’s at the sole discretion of each IO every time you arrive, so 30 days might be fine for him but not another - and they don’t really care if you have the 3 proofs, because once they determine you are not a genuine tourist (i.e. living here) then they will deny you entry no matter what...
The old days of changing passport is no longer as effective because they have your entire travel history in their system anyway...
Brooke Palmer doesn’t matter what he writes in the passport, it matter’s what the IO writes in their computer system that will flag on his next arrival.
that does not guarantee entry, I’ve been questioned twice on arrival with METV, and know of another who was sent home - due to the fact they determined the person was not a genuine tourist.
read his post correctly, he is NOT talking about reporting - he is talking about visa runs (leaving the country) and whether he has to leave every 90 days... fool
