Why did my spouse's DTV application require their own funds when I have sufficient income and savings for sponsorship?

The respondent is seeking clarification on why their spouse's DTV visa application was returned requiring financial documentation from the spouse, despite the sponsor showing sufficient funds. Community comments suggest that certain embassies, like Manila, have specific financial requirements demanding a minimum amount per applicant. It's also noted that the spouse's name may need to appear on bank accounts or statements submitted, and a sponsorship letter confirming financial responsibility might be necessary.
