i've used same map for last 8 years at CW, A4 paper, top half copy of google map CW to my house, bottom half copy of hand drawn map of main SOI to my house, covers either preference of the IO.
While the DTV appears a cheaper option upfront, your still going to paying around 10k bht pa on forced travel to keep below 180 days and possibly a couple of trips per year to immigration do your 90 day reporting (unless you travel a lot, and its a great visa in those circumstances). There is no insurance requirement for a non-O retirement visa. But if you've got the money an LTR might be a better bet.
I missed a 90 day report earlier in the year, so had to go in person to CW to do my 90 day report and pay my fine prior to my visa renewal. Rolled up ( no appointment) and asked for my que ticket at the last window nearest counter B. Rather than giving me a number ticket they gave me a priority card, which took me a few minutes to work out what it was. Hung outside the priority desk for those few minutes comparing the signage with the card and the officer called me straight in for processing. Quickest turn around ever. She read me the riot act about missing the last report though on the stroll to pay my fine at counter A. I suspect one can always ask for a priority ticket if your over a certain age.
The landlord is entitled to charge you an admin charge (same as a bank will charge you for a hard copy bank statement). Their obligation is to report your stay, not to produce a paper copy when you want one. But 500bht per person falls well outside of any reasonable charge (which most forgo). They can use the online system registering your stay from the date of filing, so no travel expenses or late filing charges need to be incurred. Ask for a breakdown of how they settled on a figure of 500bht, even 50bht for both would be ott.
I believe in both cases, and as exampled by Tod, it is full calender months, not accumatilive days (equating to an average month), therefore March 1st.
But make sure you wait to apply for it after the consideration period and you have received the extension stamp. Dont do it when first submitting your documents.
you said they dont ask for tm30 at Patong IO, (this could imply its not required to exist), unless the office has a local requirement to attach a hard copy of the tm30 to your extension form for filing, the fact they can see it on their screen suffices the need to ask for ask to see a copy, hence they don't ask. If there isn't an active one filed in the system they will ask.
