Flanked by three fellow undocumented South Florida college students, Pacheco gritted her teeth and kept putting one foot in front of the other.
Some of the Klansmen yelled epithets as the students walked a stretch of road outside Nahunta, Ga., calling them "Mexican dogs" and "homeless prostitutes," and threatening to "eradicate" Latinos from the U.S., she said.
But Pacheco and her friends, who embarked Jan. 1 on a 1,500-mile journey on foot from Miami, Fla., to Washington, D.C., said slander would not distract them from their goal: immigration reform that might bring them U.S. citizenship.
The students' so-called "Trail of Dreams," which took them through five politically conservative states, ended in the nation's capital earlier this week -- just in time for them to add their voices to the festering national debate over immigration. The four are expected to take part in a May Day immigration protest in Washington tomorrow.
"We walked 15 to 18 miles a day, six days a week, for four months to step up," said Carlos Roa, 22, from the steps of the U.S. Capitol, where the activists gathered Thursday.
"We want to put a face to the numbers" of illegal immigrants, Pacheco said. The national debate had been rekindled by Arizona's new state immigration law.
Pacheco, Roa, Felipe Matos, 23, and Juan Rodriguez, 20, say they understand the need for states like Arizona to secure the their borders -- but not at the expense of the lives of the varied immigrants who live here.
Thousands of immigrants, including Pacheco, Roa and Matos, have been in the U.S. illegally for most of their lives after their parents brought them here as children. The U.S. is the only country they've ever known, they say.
Theirs is a predicament they hope will convince lawmakers, who have been at loggerheads over immigration reform in recent months, to act. As undocumented immigrants, they are not eligible for drivers licenses, to attend college, or work legally -- and they face the constant threat of deportation.
The four were greeted Thursday on the steps of the U.S. House by three Republican members of Florida's congressional delegation – Reps. Ilena Ros-Lehtinen, Lincoln Diaz-Balart, and Mario Diaz-Balart.
"These students are Americans," said Mario Diaz-Balart. "They don't know any other place. We have to deal with that reality... They never made any decision to break the law, and to punish them for a decision that an adult may have made is against everything that we stand for as a country."
Diaz-Balart and his brother, Rep. Lincoln Diaz-Balart, are sponsors of the DREAM Act, which would provide relief for the "dreamers" and others who can prove they were brought here at a young age, have completed schooling and have no criminal records.
The measure failed to pass in 2007 when part of a broader reform effort. It has not been brought to the floor of either the House or Senate since.
It's also part of several new comprehensive immigration reform proposals, including one by Rep. Luis Gutierrez, D-Ill., and a draft framework by Sens. Chuck Schumer and Lindsey Graham. So far, however, those proposals have not been widely considered by Congress.
Schumer said Thursday that Senate Democrats are prepared to introduce their own immigration reform proposal and that "we can and should pass something" -- but no details on when.
