Following the Department of Home Affairs - a decision to implement new requirements for minors (persons under the age of 18 years on day of travel) traveling through a South African border post has been decided.
In summary: Should the legal guardians or biological parent/s not be able to produce the required documentation, travel will be denied with no compensation to the passengers. Should a minor not be travelling with a legal guardian or biological relative, guidance on the requirements of such a scenario needs to be obtained.
Please contact the Department of Home Affairs concerning any queries pertaining to the above. Alternatively contact the South African Embassy in your home country for more information.
