how do I schedule an appointment to get a passport the same day.

If you need it desperately fast call your congress representative and explain your emergency situation to them. It's what me and my dad did and we got an appointment within a day or 2

You need to call exactly 2 weeks before you fly internationally. They won't make appointments farther out. Start calling exactly at 8am. The appointments go fast.

I kept Calling every few hours the whole day, then I got the appointment for 2 days after.
