In May 2022, he was named in India's T20I squad for their series against South Africa and following month was named in the T20I squad for India's two-match series against Ireland.

In June 2022, Arshdeep was named in India's One Day International (ODI) and T20I squads for their tour of England.

In September 2022, he was named in India's squad for the series against South Africa, going on to take five wickets in two T20Is. In a Player of the Match performance during the first T20I against South Africa, Arshdeep took three wickets in his first over, including the wicket of David Miller, whom he clean bowled first ball with a sharp, late inswinger.

Arshdeep has received praise from former India cricketers Sunil Gavaskar and Sachin Tendulkar. Tendulkar commended Arshdeep for being balanced, committed, and having the right mindset for T20 cricket. He stated, "What I really like is that if Arshdeep has a plan, he commits to it and that is really, really important in this format as batters are going out and playing those extra shots and some innovative ones. So if you have a plan, commit to it."

Gavaskar praised Arshdeep’s ability to swing the ball and his temperament, comparing him to Jasprit Bumrah, and said, "I do believe that he, like Bumrah, can be a very, very good bowler in red-ball cricket as well. Because if he can move the white ball so well, just imagine what he can do with the red ball. So I think the selection committee would do very well to look at him as an option for the red-ball game as well."
