Does a Non-ED visa application require a bank statement?

May I ask if Non-ed application requires a bank statement?

My boyfriend is holding a non-b but the contract is ending this month (work permit is until September) . The school promises they could keep the work permit till September.

We're thinking of changing to non-ed for 12 months because we don't trust the school.

The agency didn't ask for statement but we're quite worried because there is only his salary account which went to another agency's account before they transfered to mine, which is not under his name.

I thought the non-ed is the easiest one.

Any advices? Thank you🙏♥️
