Versatile Bates, who can play in central defence or full-back, will travel to Wales on Tuesday to discuss personal terms.
Should the deal go through Bates could be in line to make his Swans debut away at Manchester City on Monday, August 15.
Middlesbrough have placed a £700,000 price tag on the 24-year-old.
