How can I obtain documentation for international transfers to support my A-O extension in Thailand?

Follow-up to the discussion regarding $65k international transfers in support of A-O extensions. Just got back from CW. Had a visit with Kasikorn Bank downstairs. We went through my monthly deposits and they agreed to pull each month deposit out of the monthly statement and produce a document showing the international source of each deposit. Document clearly shows the origin of the funds abroad and the deposit into the bank here in Bkk. The document even indicates the exchange rate from USD to Baht. My extension is not due so I only had them pull out six months. I was told that this document can be produced in any Kasicorn branch. Will take 5 days notice to produce 1 year and cost $500 tb . Hope this is helpful to those using the 65K monthly deposit method for A-O extension.
