Christopher to be better equipped, as I wasn't and just remembered, copy first page and last page again for them. Latest update. My previous transaction was a day before I went in, which actually was a international 40k deposit lol
Yes, I put the 400K in just over 2 calendar months prior to applying for the extension of stay, still on 60day visiting family extension - about 35 days in. I also started depositing 40K at the start of every month immediately so that is all that will be required next year. They wanted a updated bank book copy again yesterday. It still had over 400K in it and showed some spending. (I believe this is to stop people that borrow the money to do it and give back after the application is submitted?)
For others that may be converting I had one speed bump that probably has never been mentioned? As I was a on Multi Entry ImmO I acquired my Visa in Vietnam with my wifes Tabien Baan that matches her ID. We don't live there, I have never filed a TM30 as I left every 90 days... We have a lease but the landlords Tabien Baan doesn't match the address on the copy of her ID. So we had to get proof of ownership. Its a very official looking document that she was able to send as a PDF and I was able print downstairs in BKK immigration. I wont post it as I am not sure what would need to be redacted, if a mod PM I can send it and they can do what is necessary. If you do not live where your wife's tabien baan says you need to ensure you have copy of lease x2, her tabien baan x2, her ID x2, landlord ID x2, landlords proof of ownership of property x2 (If is not on their ID card) - This enables filing a TM30 for the extension of stay.
