B. You mean explanation because the proof is already there.B. I just spoke to my accountant and he said we can provide proof for big transactions and transfer from business accounts if needed. I need to show around 17K POF and my wages account should have 13K next week. The second account have 10K from long time and a 10k deposit a month back. My Indian joint account have roughly 5000 and my spouse have 10k. I think even if the case officer have issues with a particular large deposit, rest of accounts should be sufficient to cover the 17k I need to show.
C. Including my name in account is not possible, only possible thing is to open a new account and transfer money to it. Few people who have used spouse funds in past have said a letter signed by spouse is sufficient.
Bank is happy to provide me a letter that ticks everything but they have no system to generate average balance thing, so I'll attach a LOE and attach past 6 months statement alongside other signed letters.
Your 13k, plus your joint account of 5k and your wifes 10k is more than enough in my opinion.
C. There is always the option to include yourself in a bank account as a full priviledge user. Either way, as suggested, your wife's statement to the notary is enough because you clearly meet and exceed your POF even on your own given enough time.
