I got mine at chaeng wattana so I have gone to same place. And they said that they will do it only if I have an embassy letter since covid is finished now.
Today I have gone to the immigration at chaeng wattana and i have a non B covid extension visa. I showed them this form and she said that this is not applicable and can only be done for 30 days🙁.
Can we get extension at any other immigration office or should we go to the same office
