Questions regarding non o thai spouse yearly extension at Changwatanna office.

Last time I collected extension after consideration period, proof of 400k in bank wasn't required, is this still correct?

Can letter from Bank showing balance and statement bè processed the day before applying? I know bankbook must be updated same day.

Have switched to condo lease and have tm30 from owner. Does wife still need tabien bahn shown + copy? Don't live there now. And is original lease need to be shown or just copy?

Thanks in advance.
