We are from Indian state Gujarat. Patel is the most common last name in Gujarat.
90+% of Patels I know immigrated to the USA through chain migration. My dad's sister-in-law's sister (A) & her husband came to the USA in last 60s early 70s. Sister (A) applied for the immigration visa for my dad's sister-in-law. My dad's sister-in-law and my dad's brother immigrated to the USA in the late 70s. My dad's brother applied immigration visa for all his brothers & sisters. My dad & his family (including me) immigrated to the USA in the late 90s.
Roughly 200+ of us were migrated to the USA because of the sister (A). Half of them speaks & understand very very basic English. They only have limited options for the job. Mom&Pop kind of motel is easy to run, only requires talking to a few people and its mostly same every day. So they work their butt off for a few years and buy a small motel.
Those who can speak little better English end up working at someone else's hotel when they move to the USA, and from there with the friend/family's help they buy their motel.
Fellow Gujju here. It is "one" of the most common last names in Gujarat. Probably it might be the most common last name of Gujjus outside Gujarat but I doubt it is so inside the state.
One of the ways that Gujaratis come to America is use the investments route, sort of like investment chain migration. One member takes an investment, migrates, sets up business, profits, then sends the money back home, for others to travel in the same visa program. Then two people come, twice the profit, twice the pace of bringing people over. These business groups form around family bonds typically.
Most of us came to America through chain migration (Family F3/F4 Category)

For example, there was an article about how Portuguese immigrants have sort of dominated Dunkin franchises.
