Non-Thai dependent visa extension

[medkhai]

My wife (non Thai) received the 3 months dependent visa from embassy in Singapore, based on my Non-B one year visa extension.

Now it must be extended at Bangkok immigration.

What documents are required to extend her Non-O?

Thank you

She will need a copy of your passport and work permit to show you have a 1 year extension of stay, together with proof of marriage (translated in to English if in another language). A letter from your employer might also come in handy.

Her extension will be based on yours and ends when your permission to stay ends.

she will also need a copy of her passport, departure card and a pass photo.
