Danu joined the AIFF Elite Academy in 2015 under Bibiano Fernandes, where he was picked to represent India in various youth levels.[2] At the age of 15, he would have been the youngest player of India national U17 team which played 2017 FIFA U-17 World Cup. Danu, the youngest member in the Indian camp, joined the team after the Portuguese manager Luís Norton de Matos became impressed with his dribbling ability and maturity at such a young age. However, Danu suffered an ankle injury after joining the squad and the manager decided against naming him in the final 21-man squad.[3]
Due to injury, Danu was not even registered for the 2018 AFC U-16 Championship qualifiers.[4]
But later, after India qualifying to 2018 AFC U-16 Championship, he was part of the u16 team, playing friendlies in exposure trips. However, Danu could not make it to final squad of 2018 AFC U-16 Championship because the rule says that to play 2018 AFC U-16 Championship, a player must be born after 1 January 2002 and registered in the qualifiers. If not registered for qualifiers, the player must born after 1 September 2002. Unfortunately birth date of Rohit Danu is 10 July 2002. Since he was not registered in the qualifiers due to injury, he was not eligible for the 2018 AFC U-16 Championship.
