The Online Nonimmigrant Visa Application (Form DS-160) now requires applicants to provide information on all social media platforms they have used within the last five years. You will be required to provide your username, screen name, handle, or other identifier for each platform you have used, but you will not be required to provide your passwords. You will also be asked for your current email address and phone number and for any additional email addresses and phone numbers you have used in the previous five years, but you will not be required to provide your passwords.
Before you start your visa application, gather social media and past contact information and make sure your social media profiles and settings are accurate and up to date. Be prepared to answer questions regarding any public information available on your social media accounts at your visa interview.
