How can I change my DS-160 form after scheduling an appointment?

To make changes to your DS-160 form after scheduling an appointment, you will need to log in to your account on the U.S. Department of State website using your application ID and answer the security questions. From there, you can access your DS-160 form and make the necessary edits before your visa interview. Remember to print the updated confirmation page and bring it with you to the interview.
