Thanks, I have the money in the bank in case they ask again but this office only requires proof when applying (letter from bank and statement showing it's seasoned). Last year was the same. My balance will remain above 400k in case they change their mind on the day..
We did ask about the 23rd July when we applied, they said it's 30 days after my current 1 year permission is finished. We also asked about the home visit, they said not required as we had one last year (I'd even prepared copies of my neighbours ID card and blue book when we reapplied). They also told me that my wife can take my passport in July, no need for me to go!
Last year was only 30 days under consideration as it was my first time applying for a 1 year extension, prior to Covid we would go to Savanaket every year for a new multi entry non O (long drive from Mae Sai!)
