What is the experience of extending a retirement stay in Jomtien regarding proof of income and bank requirements?

I did say I would report back on my extension of stay (retirement) experience in Jomtien imm. My proof of income was the 65k+ monthly variety. My income comes mainly from one pension provider and is in excess of 65k. The SCB gave me the requisite letter and it showed every IFT - about 26 of them over the last 12 months. As I explained before the 65k+ IFTs are credited to my account on 30th of the month but as the 30th sometimes falls on a holiday, the credit shows as the following month. The checker in Jomtien noticed this but accepted the explanation. All ok, then she told me I needed a 'Bank Guarantee' letter. Had to go to nearest SCB to get it - never had to do before. The SCB (soi 11) were well up to speed on the whims of immigration so got the letter after 30 minutes. The ordeal was over after 90 minutes. The place was crowded after 10am - God knows what would happen if someone shouted "fire!"
