FYI
IEAT has approved Non O Thai Wife extension. Needed to submit Passport, WP, Thai ID wife, Wedding certificate and it was approved within 2 days, next week can pick it up and they do the 90 days extension as well., Address is company address allthough they also asked for the main address where we stay a rental for the time being.
Now we (HR and myself) know the way it is much easier than through immigration without the pictures at work, home and the visit as well as company documents and the Amphur wedding confirmation and Tabien baan.
Wish I had done this a few years ago, as it is easier, but nobody in company nor myself knew of this possibility.
