How to Fill Out the DS-11: Application for a U.S. Passport

Here are some tips from a Passport Acceptance Agent on how to fill out the DS-11 application, which is the basic passport form.
Edit: There have been some official changes in the passport application procedures since this video was uploaded. The two most notable are 1) mistakes in the application can no longer be crossed out, if you make a mistake you will need to refill out the entire page, and 2) the form itself has been updated to now have three gender markers; M F and X. The instructions on the form have been updated to reflect these changes.
