help/question - i am filling out the visa application from US and there are 3 questions I dont understand and was hoping you all would have knowledge ...

1- on the financial evidence - how many bank statements should I show? Should I upload from all my banks or just the account with the most money?

2- what does Confirmation of legal residence in a country in which you are applying for the visa mean? what are the actually needing?

3- Applicant must apply for e-Visa via specific Embassy/Consulate conforming with his/her consular jurisdiction and residency. Applicant is required to upload document that can verify his/her current residency - I don't understand what exactly they are wanting uploaded?!

I really appreciate everyone's time ( I am new to group so apologies if these questions have been asked before) - I am trying to move over in about 3.5 weeks and need to get this submitted ASAP
