NASHVILLE, Tenn. -- They are in the United States without documentation, and they are tired of hiding.

Over the past few weeks, a group of more than 30 housekeepers, day laborers, students and immigration activists has been making its way across the country in a ragtag caravan, chanting “no papers, no fear” and proudly declaring “I’m undocumented” in public gatherings.

The riders do not have the legal documents to be in the U.S., a point they want everyone they meet to know. They are on the bus tour, dubbed the “undocubus,” to highlight their plight and to challenge their anti-immigrant foes in the ongoing national debate on immigration.

“We want to live in equality like everyone else, and that's why we have taken this risk. We have confronted fear of potentially being arrested, but we believe that it is worth fighting,” said El Salvadorean Jose Mangandi, a day laborer living in Los Angeles who is raising his 3-year-old son on his own after his wife was deported. “We have customs, we have cultures. We want to share this with this country, and those who criticize us and who hate us, we invite you to get to know us.”
