On Monday, South Africa’s new visa regime comes into effect. People travelling here will have to supply their biometrics, i.e. their fingerprints, to one of our offices around the world. On the same date, new regulations, requiring that children who are travelling into and out of our country, will have to have their unabridged birth certificates with them. And, if both parents are not travelling with the child, an affidavit has to be supplied from the non-travelling parent. Predictions of chaos are everywhere. And the law of unintended consequences, for our tourism sector, our reputation, and the financial health of SAA, is about to take hold. By STEPHEN GROOTES.
