I was born in the second southernmost district of Kerala, Quilon (now Kollam). I am now a U.S. citizen in the Bay Area. Growing up in Quilon, I attended an Anglo-Indian boy's school called Infant Jesus - in a small strip of land called Thangassery, people predominantly spoke English. I was taught British dialects emphasizing pronunciations that mimicked the world stage. I didn't really understand it until much later…
The english language helped, sure, but it's the lack of opportunities in their own state and the higher education levels that created the conditions for the immigration to Middle East. Kerala also had a long history of trade with Arabs.
Yes, there is restriction on beef consumption in India but nobody protests for pork while in the middle east - it's all about which side the bread is buttered.
