In 1985, shortly after getting married, Gurpreet Gill came to the United States to live with her husband, a U.S. citizen, and his family. After she obtained citizenship, she brought her mother, who in turn sponsored green cards for her three sons, Gill’s brothers. Unable to survive on one salary, Gill had to work nightshifts to supplement her husband’s income, and she left her infant children to the care of her mother.
