I found this on Shar Gaden's website. This Domo Geshe Rinpoche was recognised by HH Trijang Choktrul Rinpoche and this is the 'real' Domo Geshe Rinpoche for me:

O fearless One, with peerless, powerful mind,
You carry the essence of Losang’s treasury,
The supreme, noble teachings of Manjusri Tsongkapa.
Please live long O Lord of Speech,
Ceaselessly spreading the instructions
On the pure view and action of the Whispered Lineage!
(This name and wish fulfillment prayer was composed and offered to Losang Jigme Ngak–Gi Wangchuk, the supreme reincarnation of Domo Geshe Rinpoche by Kyabje Trijang Choktrul Rinpoche on the 13th Day of the 7th Month in the Year 2006).
Kyabje Domo Geshe Rinpoche Losang Jigme Ngak-Gi Wangchuk was recognized and confirmed as the authentic reincarnation of Kyabje Domo Geshe Rinpoche Ngawang Jigme Chokyi Wangchuk by Kyabje Trijang Choktrul Rinpoche after careful divination, invocation of the Dharmapala, and prayers spanning a period of four years (2002 to 2006).
The previous Kyabje Domo Geshe Rinpoche was also recognized by previous Kyabje Yongzin Trijang Dorjechang jointly with Kyabje Pabongkha Dorjechang.
This holy reincarnation of one of the greatest present day Mahasiddhas was born in New York, USA on the 2nd of June, 2003, in the auspicious month of Saga Dawa to ethnic Sikkimese parents belonging to the Lingmo Kazi family who were orthodox Nyingmapas. Due to the great obstacles that usually accompany the birth of such an emanation and the degenerate times we live in, Rinpoche’s family faced unbelievable opposition and harassment. As such, it was only after establishing beyond any doubt that their son was indeed the true and unmistaken reincarnation of Kyabje Domo Geshe Rinpoche that his parents finally consented to offer their only son two years after the recognition. During this period, Rinpoche revealed himself to his parents on many occasions and the miracles that accompanied him is legendary now among his devotees. Today the parents are convinced that they have done the right thing and are happy in the knowledge that they have had the privilege of playing a positive role in the continuation of this holy lineage.
His official enthronement took place at Dung Guen Samtencholing, Darjeeling, his principal monastery in India on the 3rd of March, 2008. This joyous occasion was attended by thousands of devotees from all over the world including members of The World Fellowship of Buddhists and the Representative of the US Consulate. Thereafter, he was enthroned at Tashi Choling, his monastery in Kurseong, West Bengal; and then at Enchey House, the ancestral home and seat of previous Domo Geshe Rinpoche in Gangtok, Sikkim. On 23rd June, 2008, he was enthroned at Gangjong Namgyel, Lew Beach NY, the US residence and headquarters of the previous Domo Geshe Rinpoche. The enthronement was presided over by Kyabje Trijang Choktrul Rinpoche and Kyabje Yongyal Rinpoche. Gangchen Rinpoche, Achok Rinpoche, Michel Rinpoche and Zawa Tulku Rinpoche attended. Geshe Helmut Gassner attended as Gonsar Rinpoche’s representative. Kyabje Phabongka Rinpoche too sent his blessings and a Representative (Khentrul Rinpoche).
He was formally enrolled and enthroned at Shar Gaden Monastery on 25th April, 2009. He is presently studying here at Shar Gaden with several tutors, as well as continued contact and guidance of his spiritual Guru and Mentor H.E. Kyabje Trijang Choktrul Rinpoche.
