The Simple Rule to Remember
Do not focus on finding a magical bank balance.
You ought to rather focus on making your application credible and consistent.
Your:
Trip purpose → finances → employment/business → travel history and circumstances → intention to return
should make sense together.
And most importantly, never manufacture documents or manipulate your finances just to make your application look stronger.
A genuine, well-explained financial situation is far better than a bank statement that raises more questions than it answers.
