ORIGINAL POSTER
Hi all.

I'm just about to do my first 12 month extension on my non O staying with a Thai family member (marriage).

It co insides with us moving into a house that's just being completed. In the same province, district and sub district.

Bank Guarantee Letter

The letter from the bank showing seasoned funds, will that have my address on as I want to change my old address in due course or do I need to change to the new address ASAP?

If the latter can I go in the branch and do with my wife's blue book or do I need to get a new letter of residency from immigration to show the bank to update the address?

TIA

TLDR : Answer Summary
The user is seeking guidance on the process of changing their address in relation to their upcoming 12-month extension of a non O visa, which is based on their marriage to a Thai citizen. They are specifically inquiring whether their bank guarantee letter needs to reflect their new address and if changing the address needs to be done immediately. There are comments suggesting to consult with immigration for advice, noting that bank statements typically show only the branch address, and pointing out the potential impact of neighbor verification on the visa extension process.

Do you need a KR22 document for your extension?

My bank statements only show the branch address and not my residential address.

I would go to immigration and ask for their advice, or at least get your wife to call them.

If they want to do a home visit and talk to neighbours better to do it before you register your move so your current neighbours can vouch for you
