Jenevy Sui, 21, is to compete with Aung Htet, a male finalist, for the first prize at Strand Hotel in Rangoon on 4 July.
In the last round with only three contestants remaining, Sui made it to the final after being voted for by the four judges.
The Chin singer said that she was excited about the final competition and that she would try her best to win the prize.
From 9 pm to 10 pm on 5 July, the whole of the final competition is to be launched on Channel 7 in order for the public to vote.
Each of the two finalists is to sing four songs in total - one from their previous songs, another from the judges, the next from their favourites and the last from the public.
And the final decision is to be made up from a combination of 50 per cent from the public vote and another 50 per cent from the judges.
Salai Mang, her cousin brother, told the Chinland Guardian that Sui had started singing at church services when her family moved to Rangoon while she was a Grade-6 student.
In December last year, Sui was invited to sing at an event organized in Malaysia by Chin refugee communities.
Born to Rev. Tial Hup, from Aibur village, Thantlang Township, and Ma Nyo, of Khumi Chin from Paletwa Township, Jenevy Sui is a third year distance university student majoring in English in the country's former capital.
