What information from my cosigner do I need to lease an apartment?

I will be moving to Queens New York in August to attend graduate school. I am a student and I do not have a job. My sister, who has a steady high paying job and excellent credit has agreed to be my cosigner. When I fill out an application for an apartment what information of hers do I need to provide the landlord? Pay-stubs, credit history, driver's license, mailing address, and other contact information? Does she need to be present in person when I apply and when I sign the lease?
