The United States Post Office is the best place to go for passport pictures. The passport application can not only be acquired here, but submitted as well. The staff will know all of the rules and regulations of the photo and will most likely charge the least amount.
Go to a place that develops film, such as CVS, Walgreens, Wal-mart and Kmart. These stores will be able to provide passport services. However, it will typically take longer at one of these locations. They will place your photo in the "One hour" category. If you need to do some shopping but still need a passport photo, one of these locations will allow you to kill two birds with one stone.
For those who would rather take the picture at home, epassportphoto.com will inform you of the passport photo regulations. Go to the website and select your country of origin and the size of the passport photo. Select "Get My Passport Photo," then follow the instructions on how to take a passport photograph. While taking your own passport photo is free, you also run a greater risk of making a mistake. Unless you need a picture immediately, this should be a last resort.
In larger cities where there is an immigration office, there will typically be businesses that specialize in passport photographs nearby. They will be able to take your picture and have it developed in only a few minutes. However, these will typically be the most expensive of all the options.
