ORIGINAL POSTER

I just received approval for a Non-Immigrant O visa (90 days) for visiting my Thai family. The officer in Vancouver mentioned that I can apply for an one year extension and request a multiple-entry permit once I arrive in Chiang Mai, and that the process is easy. Has anyone done this before? What documents are required?

TLDR : Answer Summary

The user has received a Non-Immigrant O visa (valid for 90 days) for visiting family in Thailand and has been informed about the option to apply for a one-year extension and a multiple-entry permit upon arrival in Chiang Mai. Commentary from other users suggests that the primary requirement for extension is maintaining a balance of 400,000 THB in a Thai bank account, but additional requirements may vary by location. Users are encouraged to check the local immigration office for specific documentation needed.

Here’s a list for Phuket. I’ve included links for marriage or Thai child as you hadn’t specified which reason. Chiang Mai could well have slightly different requirements.

@Stuart ********

going to apply for my visa extension tomorrow and with regards the banking information supplied in the link 🔗 what is the note

***

/3 all about? Does note 3 suffice on its own. I think you can update your bank book at the atm machine if I’m right. Can I make a withdrawal and then update the bank book and get a copy made elsewhere as the banks don’t open until 10am and would like to get to the immigration office earlier than waiting for bank to open ?

Have you got a link for Bangkok information requirements specifically as this is where I will be applying and can only find general information and don’t want to arrive and find there is additional information at this bureau that I’ve missed 🫣 thanks 🙏

The money needs to have been in for 2 months prior to application. You need a letter from your bank (dated within 7 days) and an updated bank book same day of application.

Yes it can be done if you meet the requirements. The main one being 400k in a Thai bank account. The list of requirements is quite extensive but varies from office to office so you’re best to go to the office and ask for the handout that lists their specific ones.
