Application fee - You will need to pay the non-refundable visa application fee.
Photograph - You will need to provide a recent photograph that meets the US visa photo requirements.
Supporting documents - You may need to provide additional documents depending on the type of visa you are applying for. For example, if you are applying for a tourist visa, you may need to provide evidence of your itinerary, financial support, and ties to your home country.
Interview appointment confirmation - After submitting your application, you will need to schedule an interview appointment at the US embassy or consulate in your home country.
Invitation letter (if applicable) - If you are visiting the US for a specific purpose, such as a business meeting or a conference, you may need to provide an invitation letter from your host in the US.
