US demands to get access to some travelers social media handles has been in force at border controls for some time now. The latest is that this also will apply at visa applications, but still not for all.
Affected applicants would have to provide their social media handles and platforms used during the previous five years, and divulge all phone numbers and email addresses used during that period. U.S. consular officials would not seek social media passwords, and would not try to breach any privacy controls on applicants’ accounts, according to the department’s notice.
