S4 Q&A: What do I need to submit for my I-20?

 Usually your passport, financial proof at the school's required amount (an official statement under three months old, plus a sponsor affidavit if someone else's funds are used), and - if you're in the US - your I-94 and current I-20 or EAD. Transfer students add the transfer-in form from their current DSO, and anyone bringing family adds dependents' passports. Your school's portal lists the exact items, and I'll send its checklist.
