You need to be married to get the 60 days extension. The difference is only the duration. Both required a marriage certificate to be shown.

@Lynnette ******

You said: "extension of stay based on marriage". In that sentence are the words "extension" and "marriage". You said it in a different word order, come on.

@Nongnuch *******

I always called both marriage extension for practicality (you need to be married to get the 60 days...). In theory, yes, one is more of a marriage extension then the other, but the 12 months extension isn't officially called a marriage extension either.

@Graham *****

No, the 12 months is not a marriage extension. We know it as such, but the official term is not marriage extension. But in reality, yes, it's the same.

@Lynnette ******

Neither the 12 months your son did is a marriage extension either. But yet, you are still using such terminology but the difference is that you think it was the right one. Most people are like you and think that the 12 months is a marriage extension visa, it's not. I use terms that are practical because most people are not aware of the real terminologiy.

@Nongnuch *******

Neither are marriage extension, but they are known as such in the popular jargon, that's my point. Because to get the 60 days extension, you need to be married or have a child, which is the same for the 12 months. You can't get the 60 days extension without a marriage certificate or proof that you are the dad. So both are basically marriage extension because without being married you won't qualified for the 60 days extension. You are right in terminology, ofc.

@Graham *****

Yes, but it's not called a "marriage extension", but everyone call it as such. I use easy wording because Visiting Thai Family, etc, just end up confusing people.

@Steve ******

Useless to call their office. I get conflicting info every time I have ever called immigration office. I'll have to drive 2h to see if possible unless someone did it recently know for sure that it's not possible. In KK Expats group someone did it in October. I got denied in December in Udon.

@Steve ******

Yes, my wording was wrong. Most people know the 60 days extension, and the yearly extension, as "marriage extension". So I usually use that terminology. Both are for the reason you said which imply that it's basically an extension because you are married and want to see your wife.

@Nongnuch *******

@Lynnette ******

Both 60 days and yearly extension are technically not "marriage extension", as both are for "visiting Thai spouse". But it's an easier jargon to call both "marriage extension".
