Be ready to say why this school, why this course, and who pays.
Keep answers short and clear. Do not read from a script.
Bring originals, but give papers only when asked.
Check your I-20 name and dates match your passport.
Embassies can ask for different papers. Always follow the instructions on your own embassy's official page and appointment letter. Unofficial; not legal advice.
