I'm applying online and I'm at the attachments page, and I'm wondering if documents that need to be attached, like passport pages and high school records, are certified copies already? Or is there something else I need to do? I'm just confused because I've never done anything like this. Also, if I proceed to the payment part of the application without uploading documents yet, I understand it says it may delay the processing of it, but does it mean at all that my application will be denied? Thank you for all the help! I really appreciate it.
