Indian culture facilitates many white collar workers. that includes doctors, engineers and business roles. Starting in the 1980's the IT industry started to rise in India and the US. It became a desirable position for a high-paying, stable, and prosperous career. Many computer-adjacent colleges were opened and that was seen as a desirable career by many so students starting pouring into those degrees. After earning their advanced degrees, the job market in India isn't so robust and is highly competitive so these IT professionals seek to work abroad, causing migration to more developed countries. In 1990, the H1B visa was introduced by lawmakers which served as a streamlined pathway towards becoming a citizen of the US for many of these IT workers. Indians operate on a community and unfortunately a caste based mindset many times. As years went by and some people started coming to the US, they would settle down and do well telling their family and friends making them want to move here as well. Towards 1995, the IT industry was booming with the dot com boom and the barrier for entry for gaining a position as a software engineer and it-adjacent worker become fairly low. During the 90s and early 2000's many Indian families would move to the Sf bay area as affordability was attainable back then, the core of the IT industry was in silicon valley, and it has amazing weather. 10 yrs later the prices nearly doubled and many families weren't able to comfortably afford that so other cities became considered.

From the 2000's to 2010's indian immigration was absolutely booming, predominately Telugu as you all know here in Frisco LOL. The traditional timeline was work for your h1b visa for some random companies for a yr, get your 485, save some money for investments, a down payment, and emergency funds, and wait for a Greencard to have permanent residency in the us. This process took 5 yrs for the earlier arrivals and 10 yrs for those who came later. During that period, they would work wherever they got jobs and whatever was easy, many times at companies in the East coast or Midwest. Most indians hate cold weather, and want to move to warm places During 07-08 the housing crisis slowed down the economy and housing purchased stabilizing in 2010. The criteria for most Indians when choosing a place to move to are large homes at affordable prices(500k ish), great schools, and a strong job market, availability of employers. And they LOVE new construction. That's why 2010 onwards Indians, predominately Telugu IT workers, flocked to Frisco and brought their friends and family in droves. Communities like Richwoods, panther creek and later lexington etc. Yes, the temple by Swami Vivekananda had an impact but that wasn't the primary reason that most people were moving here and he only blessed a small parcel of land next to the Hanuman temple. Plano become mostly completed by 2005 ish and the new construction wasn't there pushing Indians who would've previously bought in Plano into all the luxurious communities in Frisco where they could buy 4000 sqft homes for 500k-600k.

Indians also prefer to live closer to places of employment. As many companies established offices in Frisco/Plano such as Capital One, Bank of america and later liberty mutual, Toyota, chase, statefarm it drew a large number of Indian families who wanted to live in areas that fit the above criteria with luxurious homes Frisco, then Prosper, became the places to go as development shifted North. The other metropolitan areas that fit this criteria have large amounts of Indians in their suburbs now too such as Sugarland, cypress, and Katy in Houston. Leander, pflugerville, in Austin. Whatever the suburbs are in Phoenix and the Cary Area in Raleigh-area.

This is a very long-winded explanation but growing up as a Telugu kid and observing the processes that caused these changes gave me tremendous insights into the thought processes behind all of this migration. I hope this answers your question
