Find a white or off white wall and have your subject sit in front of it facing the camera with a natural expression on their face; not smiling.
Frame the picture so your subject's face is in the middle of the screen and take the picture.
Review the photo you just took and make sure your subjects eyes were open, their mouth was closed, and they were facing directly at the camera.
Upload the photo onto your computer and load it into your favorite photo editing program.
Crop the picture into a perfect square, so that the face of the subject is at the top of the square and is not being cut off on any side. Your subjects face from chin to hair should be between 1-inch and 1 3/8-inches of the entire picture and not tilted to either side.
Use the printing preferences options in your photo editor to adjust the picture size to 2-inches.
Print two identical copies of your picture on thin photo-quality paper and submit them along with your passport application.
