The American has not featured at a Grand Slam since giving birth last year, with the 36-year-old dropping to 449th in the rankings as a result.
Williams, who claims players should have protected seedings on top of protected rankings, is expected to feature at the French Open, having last played in a Grand Slam when she won the Australian Open last year.

World No 1 Simona Halep said at Indian Wells that Willaims should be given the top seed, and that could remain the case, according to the All England Club.
The club told the BBC: "The seeding order follows the WTA ranking list, except where in the opinion of the committee, a change is necessary to produce a balanced draw.”
Meanwhile, should Andy Murray remain out of the men’s top 32 going into Wimbledon, the Briton will not be handed a special seeding.

Murray is on the comeback trail having last played a competitive match at last year’s Wimbledon, but the All England Club have agreed with the ATP that players must be within the top 32 before an amendment to the seedings is considered.
"We take into account grass-court results from preceding years but the agreement we have with the ATP is based on computer formula," said Richard Lewis, chief executive of the All England Club.
"Andy wouldn't be put in the top 32 if he isn't in that formula."
