Hi all. Apologies if I am asking something already asked. I've been searching and looking but I'm still confused!

My mother in law (Israeli passport) is visiting. Entered with 45 day visa exemption. She wants to stay a bit longer and needs an extention (she'll be staying 60 days total).

We live in Bangkok.

1) Which immigration office do we need to go? Is it only the one at Laksi that we can go to? My mother in law is elderly with some serious mobility issues so we wonderd how accessiblwe the offices are and where she can sit and wait somewhere while my husband waits in line. How acommodating are the offices for disability?

2) What do we do about the TM30? We rent and she's just been staying with us so hadn't crossed my mind until I read the posts here. Do I need to get my landlord to do something (my landlord is not a helpful person)? The links to register online require documentation that only the landlord would have.

Thank you!
