What size photos do I need to apply for an American visa?

1. You need a 50×50 mm color photo with a white background to apply for a US visa.

2. Embassies in different countries have different requirements for visa photos, and the most common one is passport photos, that is, two-inch color photos with white background. Some embassies have detailed regulations on the color, size and clarity of photos. For example, India needs color photos with 4*3.5 blue background, and the United States needs color photos with 5*5 white background.

3. Visa refers to the procedure of endorsement and seal of passports or other travel documents held by domestic or foreign citizens by the sovereign organs of a country to show that they are allowed to enter, exit or transit. It can also be said that it is an endorsement certificate issued to them. Generally speaking, a visa is a document issued by a country's entry-exit administration (such as immigration bureau or its embassy or consulate abroad) to approve the entry of foreign citizens.
