The performance was part of the semi-finals and after that mesmerising performance and the judge's glowing remarks, the duo is through to the final round.
Ms Tulasi's father was from Hyderabad, India and her mother is from Moscow. She says learning Indian classical dance helps her learn more about India.
"Great to see an Indian traditional dance at a foreign land," comments Soumya Pahuja on the video.
"Congrats and best of luck Svetlana, you make India and Russia proud, keep doing the good work," writes Prajwal Hegde.
"I have seen many people perform Bollywood Kathak but this was the best," adds Shashaank Dey.
Ms Tulasi previously participated in Ukraine's Got Talent. She recently made her Bollywood debut with a supporting role in Imtiaz Ali's Tamasha, starring Ranbir Kapoor and Deepika Padukone.
