Earlier in the day, in the men's singles event, Verma dished out a dominating performance to beat the 10th ranked Tommy Sugiarto of Indonesia 21-16 21-7 in a 40-minute Group B clash.
World No 14 India qualified for the year-ending tournament at the last moment after defending his title at the Syed Modi International last month.
The 24-year-old Indian had lost the opening match against World No 1 and world champion Kento Momota.
Sameer, who had come into the tournament with a 1-1 head-to-head record against Sugiarto, looked comfortable the Indonesian as his sharp game made life difficult for his opponent.
The Indian lagged 1-3 and 5-6 initially but he soon wrested the lead with four straight points before entering the break at 11-7.
Sugiarto tried to stage a comeback and narrowed the deficit to 16-17 but Sameer reeled off the remaining four points to earn the bragging rights.
In the second game, Sugiarto again took a slender 5-3 advantage but the Indian stamped his authority to move from 7-6 to 16-6 with a nine-point burst, and then slammed the door on his rival with another five straight points.
Sindhu takes on Beiwen Zhang of China. They have 3-3 head-to-head record, but the Indian shuttler should start as the favourite against the eighth seed American.
Later in the day, Verma will take on sixth-seeded Kantaphon Wangcharoen of Thailand. They have met twice before, and the head-to-head record stands at 1-1.
