Re Bank Statements: I am not using the method of 800,000 Baht funds in the bank account, seasoned for three months, nor an up to date letter from the bank manager. I provided a Letter of Income from the British Embassy, dated November 2015, as proof of monthly/yearly income. I understand this letter must be obtained each year although any letter within 6 months of the date of extending one's permission to stay is acceptable to Immigration. Therefore, how much I have in the bank today or yesterday should not be relevent.
From an earlier discussion a year ago, I was informed that Immigration wished to see 12 month's worth of bank statements in addition to the letter from the Embassy. This was to support the figures shown in the income statement but, more importantly, to see where your money was coming from i.e. monthly bank transfers from the UK or wherever. In other words, that your income is derived from overseas and not from any illegal activities in Thailand. I had given the desk officer my bank statements for the previous 12 months, albeit only up to the third week in November. FYI, my trip to Immigration was delayed from my intended date of 2 Dec 15 due to my extended stay in hospital. Hence the slightly dated bank statements (only 3 weeks missing). So Mr Coffee, far from not knowing that I must know better I had taken my updated bank passbook with me as a just in case. In the event the desk officer politely informed me that he did not want to see it. Sometime later, at 1930 in the evening to be precise, my wife received a phone call to tell me to bring the bank book with me next time around. WTF!
