Bantwana, Nigeria and Ghana are the three African teams that have qualified for the tournament in Trinidad and Tobago in September.
Bantwana coach Solly Luvhengo said they will play a friendly against Trinidad and Tobago on September 2, after friendlies against England in London on August 17 and 19.
Bantwana will be in England for a training camp from August 14 to 19, said Luvhengo, who is assisted by Joseph Mkhonza.
"We usually take 18 players along for the qualifiers, but Fifa require us to select a team of 21 players for the World Cup in Trinidad and Tobago," Luvhengo said.
"We need three new players to beef up the team. Our aim is to take a razor-sharp team that will make South Africa proud in Trinidad and Tobago.
"England are always a force to be reckoned with and were fourth in the last instalment of this tournament, which was won by North Korea in New Zealand two years ago," he said.
