Upto her i guess... ideally shudnt happen.. if u have a bank book use that and get its copy stamped by the bank... 100 baht charge ofcourse.. but if u just need for yourself its easy to fetch that from the app
Downlaod section38 app and just register to it using the blue book for that house ... That way no need to visit any places. Everytime u enter can just update the entry on that app..
sorry i have no leads on indian agents who can iniate the visa process from india.. u can ask for info in 'Indians in Thailand' group. So i would suggest that look into retirement visa option for your mum when she is here... but first step is definately the 60 day Tourist visa for u to go with
technically its shud be 30 days extension..but the immigration refuses to give it for indian nationals ... in some cases the agents can do it for u ..but thats gonna take more than 1900 baht obviously. Talk to a few reliable agents regarding this .. i am gonna try to extend it for myself aswell .. lets see how it goes
U can get an agent to do it fro u from vfs kolkata. Pls note : Tourist visa is only for 60 days stay and 7 days extendible for indian passports. Multiple entry option is still not available right now.. but that might change from July onwards.. refer to vfs website for more details.. unfortunately the online option has still not resumed in Indian VFS offices.. better to consult an agent
