I think it is several factors.
First was British Colonialism that spread Western Civilization and the English language to India. Then the technological revolution gave to the best and the brightest young people in India, young engineers and computer people, new opportunities that have swept away many traditional limitations and brought them to or in contact with the US.
One of the biggest factors in the growth of Objectivism in India was ONE PERSON – the late Tara Malkani. Here is an article about her that ran in the CyberNet:
We were sad to learn of the death of TARA MALKANI, considered by many
to be the “Mother of Objectivism in India,” on September 26, 2000.

Tara was, I believe in her mid seventies. She was an executive in
Indian Airlines’ personnel department until she retired in the
late 1980s. She was very athletic and kept playing in tennis
tournaments well into her sixties and she was a passionate
swimmer. After her retirement from Indian Airlines Tara remained
as busy as ever by giving swimming lessons in various places and
giving “grooming” lessons to aspiring flight attendants.
Tara discovered Objectivism in her mid-thirties and was a
passionate advocate of Objectivism from the start. She ran an Ayn
Rand Readers’ club at her home in Bombay and put ads in the
newspapers about the club – and that’s how she met her husband
Govind. The club was informal and interested people would drop in
every Saturday evening and either engage in discussions or just
enjoyed Tara’s vast collection of Objectivist material.
On a personal note: I came to know of Tara in 1990 when Dr.
Michael Berliner suggested that I contact Tara. I corresponded
heavily with Tara for the next two years and after her repeated
invitations, even visited and stayed with her in Bombay. Tara has
amassed a gold mine of material on Objectivism including videos
and audio tapes and it was at Tara’s place that I first got to
watch The Fountainhead and We The Living movies and almost all of
Miss Rand’s video taped lectures along with video lectures of Dr.
Peikoff, Dr. Harry Binswanger and others.
Authorized by the ARI, Tara also loaned out taped lecture courses
to other Objectivist clubs in India and that’s how I was able to
listen to four of Dr. Peikoff’s lecture courses.
Tara had to go through some very tough times in the early nineties
on account of Govind’s serious health problems but nothing
deterred her from attending annual Ford Hall Forum lectures and
other Objectivist events in America and England. She took great
pride in getting all sorts of Objectivist material as soon as they
came up for sale and treasured her autographed books by
Objectivist authors. If I recall correctly, Tara also attended the
last Ford Hall Forum lecture given by Miss Ayn Rand and got her
copies of The Fountainhead and Atlas Shrugged autographed by Miss
Rand.
Tara was a major donor of the Ayn Rand Institute and she loved
telling stories. One of her favorite ones was how she first met
Dr. Michael Berliner and made her donation to the Institute by
presenting a solid gold coin which she had smuggled past the
customs and how Dr. Berliner was thrilled by her gesture.
Tara was physically very active until about 3 years ago when,
after surgery for cancer, she completely lost her hearing and her
overall health was also affected. Given her love of physically
active life, it must have been particularly hard for her but her
enthusiasm about Objectivism remained undiminished.
Tara is survived by her husband Govind and her many friends in India
and all over the world who will miss her terribly and remember
her fondly.
