Rawat, who previously starred in Numb3rs, will play a woman called Kendra when she appears on the show.
"My character starts out as the girl next door, but it turns out she's not at all what she appears to be," Rawat told TV Guide.
"Fiona [Gabrielle Anwar] is investigating a case when she firsts meets my character, who is involved in her neighbourhood watch programme. I appear to be a good, upstanding citizen but it turns out she has ties to the underworld. She's a pretty explosive surprise."
Rawat added that she loved working with Jeffrey Donovan, who plays Michael Westen.
She said: "I was very excited to work with Jeffrey and had a wonderful time with him and was made to feel very much at home."
Burn Notice continues on Thursday at 9/8c on USA.
