If your photo upload fails, you should submit one printed photograph with your DS-160 confirmation page to the U.S. embassy where you are applying.
Your printed photograph must meet requirements set forth by the State Department in order to be accepted. The photo must be in color, sized such that the head is between 1 inch and 1 3/8 inches in height, taken within the last six months, taken in front of a plain white or off-white background, taken in full-face view directly facing the camera, taken with a neutral facial expression with both eyes open and taken in clothing that you would normally wear on a daily basis. With the exception of religious clothing and headwear, you should not wear a uniform, hat/head covering or glasses in your picture.
As always, please do not hesitate to contact Garfinkel Immigration Law Firm by phone at 704-442-8000 or via email with any additional questions and to receive more information.
