, I guess the question is if the seasoning is broken if the account during one day is going under 500k even if the 500k is there in the morning and again in the evening?
We can explain the scheme of the requirements but the exact list of documents differs from immigration to immigration. 1) You will have to prove you have the money - one way or another also depending on your Embassy. 2) You will have to prove your marriage is still valid with a document from the local Ampour, 3) You will have to document your right to stay where you stay with a document from your house lord. 4) Some pictures of you and your wife at your house, 5) A handwritten road map to your house, 6) More...
, it is much more complicated to get a one-year extension based on marriage compared to based on retirement in respect to paper works, but possible if you carefully provide all the documents needed.
, the list from Phuket seems more or less like the minimum requirements everywhere. The details are the difficult ones like how many pictures from your house, and how many documents from bank or embassy. Prepare yourself that this process is very bureaucratic and will easily take a number of visits to the Immigration if this is the first time you are getting an extension. Can only repeat to keep a full copy for next years to come.
, then try using the list from Phuket and they will tell you what is wrong or missing. Remember to keep a copy of all documents in correct order to make next years extension easy.
