Yes, everyone I know in the program has to show their bank statement proving deposits and expenditures.
In today's world with many people retiring without a defined pension plan and maybe before they are old enough to collect Social Security, if they are qualified for such, people who apply for the program have to prove they actually have funds in a slightly different way. Statements from accounts where these funds will be withdrawn from will be accepted I believe provided their are what the country considers sufficient funds. (please don't ask because I do not know what that level is)
