There are a thousands reports in this group from successful applicants. Choose the embassy you'll be using and use the group search tool to research. Best to use a single account.
Depends where you're applying from but mostly if you're applying in Southeast Asia prepare to show at least 3 months of 500K that said, if you had a substantial balance and you ended up topping it up in the last month that would probably work too for instance if you had two three 400k and topped it up to 500 in the final statement but again you'll have to review the posts on the specific Embassy you're going to be applying at.
A. Nony Mous The OP is asking about the 500K balance, yes I have seen embassies request the latest months statement and 3 months statement with an ongoing 500k, but never a 6 month statement. Embassies have requested 6 months statement to review the account activity but not because they wanted the 500k to be in there all that time.
