 Some Sikhs worked in lumber mills of Oregon or in railroad construction and for some Sikhs it was on a railway line, which allowed other Sikhs who were working as migrant laborers to come into the town on festival days.A big effect on Sikh migration to the western states occurred during World War I and World War II, where Sikhs were recruited by the British Army to serve for them.Sikhs fought bravely during these wars and began to live in England after their serving period.
