Hi everyone. If I'm extending my child's (minor) tourist visa, do I require written permission from the other parent as well?

Hi there, seeking advice about a visa transfer. We will get our visas renewed in Bangkok (living in Chiang Mai) - but need to transfer my daughters visa to a new passport shortly afterwards. Does anyone know of any reason we couldn't do that visa transfer in Chiang Mai? Or is it necessary to do that in Bangkok because that's where our visas are renewed? Many thanks...

Hi I forgot how many months old bank statement for non O Thai child extension for 1 year, 2 or 3 months and if my visa finish 8/8,is enough time to go week before? TIA
