I need to renew my marriage visa (married to Thai wife) next month and just need to see if I'm missing anything from my checklist. So far I have:

• Wife's ID + Passport
  
• My Passport.
  
• Tabien Baan
  
• Bank book showing 400,000 Baht deposited for at least 3 months.
  
• Letter from the bank certifying the balance.
  
• Original Marriage Certificate
  
• 3 Passport-sized Photos.
  
• Photos of us in our home (Front House, Living Room, Dining Room, Bedroom)
  
• Map from the Immigration to our house.
  
• 3 Copies of everything above, including all passport pages.
  

Am I missing anything?

Last time I went I also need a letter from my wife stating we were living together and still married.

Take the wife

Do not forget to take your Wife to be interviewed and sign the affidavit.

Some Immigration Offices now require the Sor Kor 2 paper from the Amphur. (Copy from the Marriage Register Entry). You will have to ask them if it is needed.
