What is a one-sentence summary of the following article?
The consular official should tell you what you need to bring in advance of your interview. For example, you will probably need the following:  confirmation page to Form DS-160 receipt for payment of the application fee passport photographs if you couldn’t upload the picture evidence you intend to return home after your trip (some applicants) evidence of your ability to pay for the trip, such as bank statements (some applicants) When you arrive at the consulate or embassy, show your appointment letter to the guards. An embassy or consular official will check to make sure everything is in order. You will then talk to a different official, who may ask you questions about your job, education, and your plans while you are in the U.S. Answer all questions honestly.  The interviewer wants to see that you have sufficiently strong ties to your home country so that you won’t try to stay in the U.S. permanently. If you are traveling for medical treatment, you may need to provide a diagnosis from your doctor and an explanation of the treatment you are seeking. In some countries, you must pay an additional issuance fee. You can check how much you will pay ahead of time by contacting your embassy or consulate. You can also check the State Department website and enter your country. Digital, ink-free fingerprints will probably be taken during your interview. However, each consulate or embassy is different, so you may give them at a different time. If you are approved, then arrange for the delivery of your visa. For example, you can usually pay at the consulate for a courier to deliver the visa to you. The average processing times will differ depending on the embassy and your personal situation, but 3-5 business days is typical.

Summary:
Gather documents. Answer questions. Pay an issuance fee. Give fingerprints. Receive your visa.
