The women will walk 100 miles from Pennsylvania to Washington to experience a papal visit that has excited immigration activists. The pope has called on countries to adapt more compassionate immigration policies.
Among those making the trip is Ezzie Dominguez of Denver. Although she is a U.S. citizen, her husband is stuck in a seemingly never-ending naturalization process.
"We are not a statistic. We're not a name," Dominguez said. "We are human beings that are suffering.”
Pope Francis will address Congress, where he could talk about immigration issues. He is expected to meet with immigrants during a visit to Philadelphia two days later.
