CIUDAD JUAREZ, Mexico — Six years ago, the four Contrera siblings — two sisters and two brothers — left their native Venezuela to move to Ecuador, joining a mass exodus from a country riven by economic distress and political upheaval.
Last month, the four decided to relocate again, this time thousands of miles away to the United States, where tens of thousands of their compatriots have been admitted in recent months.
They traveled through Mexico and last week presented themselves to U.S. border authorities in El Paso, Texas. After being briefly detained, the brothers were released — they joined another sister in New Jersey — while the sisters were sent back across the border to Ciudad Juarez.
