You MUST include one photo with your passport application.
And while you can take the photo yourself, we don't recommend it.
One of the biggest reasons passport applications get delayed is a bad passport photo.
So while you might think you are a great selfie photographer it doesn't mean you can take a great passport photo. Forget it!
Have your photo professionally taken by a professional photographer who knows how to take passport photos or get it done at an authorized location. Check our Where to Get Your Passport Photo Taken page for a list of locations and prices.
