when i picked up my yearly extension from cw (thai child) after 30 day consideration, i had to produce updated bank book. no problem but i didn't have to last year.
i was gonna say i'm confused by the 'report' and the 'registration' words u used in ur reply.
just to make it clear - i do my 90 day reports religiously online with full acknowledgement from immigration.my last one was 3 weeks ago
basically, i did my LAST extension of stay in september 2018. they did ***not **** ask me for a tm30 last year. since then, i hv not stayed away from my residence AT ALL so when they do the check, they will not find a record of my passport being submitted by a hotel or a guest house or upon leaving the country.
