"Also, for the visa, if it would be paid via financing, what do you show for the financial statements?"
Not sure what you mean here.. Are you are talking about financing the cost of your training ? If so then the money should be in your bank account from whatever finance source you use prior to going for your visa. The officer will need to see that you have finds to cover your stay i the USA for the duration of your training. Maybe I am not understanding your question correctly as I imagine it is unlikely you would need to finance the cost of your PPL based on your previous posts.
