S3 Q&A The school is asking again for my passport, I-94 or I-20 copies.

 That's routine - schools often re-request status documents at the I-20 stage or when an earlier copy was unclear. Upload clean color PDFs: your passport bio page, your latest I-94 from the CBP website, and every I-20 you've held. If anything has changed since you applied, such as a new I-94 or EAD, send the new version.
