Hi. A quick question

My wife and I are going to Thsi Immigration in Udon Thani tomorrow where I am applying fir the 1 year Marriage Visa. I have all the documents in order and will stop off at the bank prior to going in to get the letter confirming 400,000 on deposit now for over a year. Reading thru the requirements, as I am retired, I wondering if I need a letter from Gov't of Canada saying I have a minimum of 40,000 Baht per month. I do not have such a letter. Your speedy response would be greatly appreciatec. Thank you.
