I entered Thailand on 6th Dec 2021 on a Non-Immigrant 0 (Family Visa - Thai Wife) with 90 days from London Embassy.

I recall I can extend this at Cheng Wattana; can someone please advise what is the maximum it can be extended? (My return flight has been delayed so it now falls just outside the 30 days).

Am I also correct in that I can only go to CW 14 days before expiry? Will the extension be from the expiry date or the date I go to CW?

 

You can obtain 60 day extension "to visit wife". The extension will start from end of current permit. 

Good option. 

If you were remaining in Thailand you could have obtained 12 month extension.

Just mentioned for future visits. 

You can apply for a 60 day extension to visit your wife. She will have to be with you when you apply.

You can as early as 2 weeks up to the day your 90 days ends. Your extension will start from the end of the 90 days.

Many thanks Joe for your prompt reply ????
