Less hassle would be to come visa exempt for 45 days, and extend for 30. But if you are dead set on 90 days at a time, then you had better get on that visa now.

Although that info is currently not being requested, so...

@Andrew *******

it may help if you stay in a hotel on occasion for a day or 2 on entry. I would think the same local non hotel address would raise flags as well. Just my thoughts. And maybe stay at a hotel for a night once a month?

Good to know.

@Christopher *************

how was the Hilton? I have always wanted to do a couple nights there.

Quick question, are you registered as staying at the same address the whole time? I wonder if that gets alerted.

But to be on the safe side... Have an outbound ticket. 🙂

Correct. And only show the ticket if asked.

I have heard this many times as well.

To be absolutely safe, you should book a quick flight to a nearby country like Malaysia, Vietnam, or Cambodia etc. Heck, take the 3 day excursion. It will save you from having to go get an extension.

Some people use a service to book a "throwaway" ticket.

Some people will press their luck, and if their airline denies them boarding, they will quickly go online and book a flight. (Luck of the draw on the prices you will find). Thai immigration is not as easily satisfied I don't think.
