英国（United Kingdom）签证或护照照片要求

The photographs must be:

• identical;
• recent (taken within the last month);
• 45 millimetres (mm) high x 35 millimetres (mm) wide (please do not trim your photographs to meet this condition);
• taken against an off-white, cream or light grey plain background so that your features are clearly distinguishable against the background;
• printed on low-gloss, plain white photo-quality paper (with no watermarks, embossing or printing on the back);
• undamaged, for example, by creases from paperclips;
• of you on your own (no toys, dummies or other people visible);
• a close-up of your head and shoulders so that your head, from the bottom of your chin to your crown is between 29mm and 34mm high; and
• clear of writing on the front and back.

The photographs must also:

• be in sharp focus and clear;
• have a strong definition between the face and background; and
• be printed professionally. Photographs printed at home are not likely to be of an acceptable quality.

The photographs must show:

• no shadows;
• you facing forwards, looking straight towards the camera;
• a neutral expression, with your mouth closed;
• your eyes open and clearly visible (with no sunglasses or heavily tinted glasses, and no hair across your eyes);
• no reflection or glare on your glasses, and the frames should not cover your eyes (you may find it easier to remove your glasses);
• your full head, without any head covering, unless it is worn for religious beliefs or medical reasons; and
• nothing covering your face. Please make sure nothing covers the outline of your eyes, nose or mouth
