Just submitted my application online in the US, all it asked for was my employment contract and one bank statement, and identity documents, including proof of living here. I had a bunch of other documents to submit, but there was not an option to submit additional documents online. It now says pending. Is there a way I can submit other documents, or I just need to wait? Just read another post where the person was denied without explanation or a chance to supplement and I don’t want to get denied, without the chance to submit all the extra material I had. Any suggestions? 
TLDR : Answer Summary
After submitting your online visa application, you typically cannot submit additional documents once the status is pending. It's recommended to combine multiple documents into a single PDF for future submissions. If you feel additional documentation is crucial, you will need to wait for a response and inquire about submitting further materials.
