The Boks are due to defend the title in Australia between 7 November and 12 December, but several hurdles needed to be cleared if it is to be confirmed.
The South African government lifted the ban on international sporting participation a week ago and directions to manage such participation were published on Wednesday evening.
A spokesman said that SA Rugby was seeking further clarification from the departments of Arts, Sports and Culture and of Transport as to how those regulations would impact on the planned participation.
A final decision was only likely to be finalised early next week once those clarifications had been assessed internally and with SA Rugby’s SANZAAR partners.
