I applied for a passport 3 weeks ago because I am traveling to Canada on June 6th. While waiting for it, I got a letter from the U.S. Department of State to make a copy of my California ID (because I sent my student ID and it wasn't enough). I make a copy of my ID and the letter they needed and want me to send it back to them with the envelope the attached inside the envelope with the letter they gave me. I'm ready to send it, but there's 3 lines I have to fill in which I don't know what stands for.
1. Departure Date (I'm assuming it's the day I am leaving?)
2. Attn (I honestly don't know what that means.)
3. App.# (My application number for my passport?)
Am I right about 1 and 3 and what is 2?
