The first significant period of modern migration from Indian began in 1965. The second wave began in the 1980s with family reunifications. During the last decade of the twentieth century and the early twenty-first century, a sizeable Indian community emerged in Lowell, which serves as a gateway for many Indians who are temporary residents, or to those who eventually move to more suburban areas. This wave of approximately 3,500 people included graduate students, well-educated professionals (many arriving on an H1-B Visa), and people working in the service sector. A vibrant and active Indian community centered around Middlesex Village contains shops and restaurants. Two Swaminarayan temples draw crowds of hundreds for weekly and monthly religious services.
