Do I need to bring previous visa extension documents when applying for a Non-O visa extension at a new immigration office in Thailand?

Is the monthly income lowered to 40k? I was told 65k

I have never heard that was a reqiurement at C/W when getting a new extension after previously getting them in a different province, and don't believe they will require those documents,

BUT

it's probably a good idea to have them IF you moved provinces/offices, just in case 🙂 I wouldn't give them to the officer when you apply, but have them if you're asked about it.

Make sure you have a new TM30, have been doing 90 day reporting at C/W (if you have had to) and have all the required documentation showing you now stay in Bangkok (lease, owners thai i/d, house book etc)

Also make sure you have the new photos, (you two standing in front of your address numbers, you two sitting inside the house [two/three photos].

These are the requirements to get a year extension based on marriage to a thai (just ignore the 400K baht financial requirements as foreign females married to thai males are exempt from that). This is not office specific, but is just a general list that will get you 'in the ballpark' 🙂
