Just wondering what is require to RENEW visa the second time.  Do you need ALL the same documents as the first time?  Does your wife need to come with you again?  

I presume you mean extension of stay based on Thai wife.

Yes. Exactly the same documents as the first time. Yes your wife must attend. Many offices require a new Kor Ror 2 for each extension. Best to check with your IO for exact requirements.

There is a check list available at immigration.

2 copies everything required including the photos.

If you are asking about a 12 month extension based on Thai Wife same procedure every year.
