The immigrants staying put in the U.S. for now include Narcisa Marcelino, 34, a single mother who lives with her two daughters, ages 10 and 5, in Martinsburg, West Virginia. After crossing into the U.S. from Mexico in 2000, she followed her brother to the eastern part of the state just outside the Baltimore-Washington region. The Martinsburg area is known for hiring hundreds of migrants annually to work in fruit orchards. Its Hispanic growth climbed from 14 per cent to 18 per cent between 2000 and 2005 before shrinking last year to 3.3 per cent, still above the national average.
