Immigration will not know where to go for the home visit, and the photos you submitted with your application will not match. Also they normally want to talk to neighbors to verify that you live together with your spouse. All of these are difficult to prove if you move between those times.
You need to go to the immigration office that you got your extension from to transfer the stamp. You should do it before you leave Thailand again, as the airport people will get cranky knowing you had the opportunity to do it already but did not.
There's no such thing as a TDAC entry. The TDAC is an entry card, that replaces the old TM6 paper. It has absolutely nothing to do with your being allowed to enter or not or how many days you will be allowed to enter for. It's just an entry card.
You've been in Thailand for less than 2 months this year, you shouldn't have any issues entering, especially if you have proof of your ticket out of Thailand within 60 days.
If you've already been in Thailand for 230 days this year, you are "living in Thailand" and are very likely to encounter issues entering visa exempt. You have a Thai wife, why do you not just apply for a non-O visa based on that? Then you won't have any issues at all.
Also, there is no such thing as a European Citizen, nor is there a such thing as a European passport. Thailand admits people based on the nationality of their passport, and there is no European passport.
You cannot renew a visa. You can apply for an extension of stay. It's a brand new application every year. Nothing is renewed.
The expiration date of your permission to stay is in your passport. You can apply for an extension when you have 30 days or less left at most immigration offices, and 45 days or less left at some offices.
Latest reports I've read were 2-3 weeks in Laos. Visa issued shortly after interview. Some people had luck emailing and requesting and interview sooner after they were given a date and time.
I have his original profile blocked, so I cannot even see what profile his nickname is tied to. Tod McGowan too. Actually I have a lot of people blocked.
