Though Congress authorized up to 5,000 T-visas per year, fewer than 700 had been issued overall as of September. Some victim-support experts say the relatively low numbers result from overly strict criteria, notably the requirement that victims assist prosecutors.
"It can be a very difficult decision to come forward and begin a criminal complaint when a victim has every reason to believe a trafficker can make good on a threat against family members," said Steglich, the Chicago immigrant rights attorney.
"There are concerns we're not able to do all we can for those victims who don't want to come forward. We'd like to see more flexibility."
Federal officials defend the rules as necessary to separate fraudulent claims from genuine trafficking cases and to put traffickers out of business.
"The cooperation requirement is essential," said Bradley Schlozman, the Justice Department's acting assistant attorney general for civil rights. "These traffickers are extraordinarily evil — if a victim doesn't come forward, that trafficker is going to turn around and exploit other individuals."
Wade Horn, assistant secretary for children and families with the Department of Health and Human Services, said reaching victims and getting them to speak up is a key goal of a new federal program. A national hot line has been set up, fielding more than 2,500 calls to date; the hot line is being advertised in ethnic newspapers and printed on matchbooks distributed in places where victims might find them, such as ladies' rooms in bars and fast-food restaurants.
"The problem is the traffickers are very good at controlling their victims," Horn said. "They don't have access to TV, their ability to learn English is restricted, so getting the message directly to the victims is difficult."
Anti-trafficking task forces have been established in 22 areas nationwide, and training sessions are being held for social workers, health care workers and police officers to educate them about trafficking.
"A cop arrests some street prostitutes, puts them in jail and tries to get someone to deport them — that's exactly what traffickers say to their victims," Horn said. "The cops think they're just doing what they're supposed to do. ... We're training them to know what to look for, what to ask."
Some victims are forcibly abducted to the United States by criminal gangs, but many come willingly, swayed by promises of good jobs or marriage that turn out to be false. Their documents are confiscated by their traffickers, and they are forced into slave labor or prostitution.
Maria Suarez, for example, came from Mexico to Los Angeles legally in 1976, a naive 16-year-old with sixth-grade education and no English, hoping to find work. She was offered a housecleaning job at the home of a 68-year-old man who instead converted her into a virtual slave — threatening her and her family if she told anyone of the rapes and beatings that ensued over the next five years.
In 1981, the man was killed by a neighbor; Suarez agreed to hide the weapon, was convicted of conspiracy to commit murder and sentenced to 25 years to life. Officials later confirmed Suarez's claim of being a battered woman; she was paroled in 2003 and subsequently certified as a trafficking victim eligible for a T-visa. She can stay in the United States at least though next year.
Now 45, Suarez attends Pasadena City College, hoping to gain U.S. citizenship and become a social worker. She urges authorities to be understanding of sex-trafficking victims who are reluctant to speak out.
"It was a disgrace," she said. "How was I going to confront my family and tell them what was happening to me?"
Had the neighbor not killed her abuser, "I would have died there," Suarez said. "I was too scared to tell anyone what was happening. You're overwhelmed by threats of harm to you or your family."
Prior to the Trafficking Victims Protection Act of 2000, no comprehensive federal law existed to prosecute traffickers. Since 2001, the Justice Department says it has prosecuted 277 traffickers — a threefold increase over the previous four years — and has obtained convictions in every case.
Schlozman said the Justice Department is intent on combatting all types of trafficking, but estimated that about 75 percent of the prosecutions involved sex trafficking.
Some victims' advocates say the government stresses the sex cases because they generate more news coverage or because they are the priority of conservative Christian groups that form an important part of the Bush administration's political base.
"Christian evangelicals see this as an important mission — rescuing women from sex trafficking," said New York University law professor Michael Wishnie, a specialist in immigrant labor issues. "There's a risk of distracting attention from much more common situations (in sweatshops) that many more people find themselves in."
Wing Lam, head of the Chinese Staff and Workers Association in New York City's Chinatown, tries to assist low-paid workers who are abused by their employers but may not qualify as trafficking victims.
Many pay to be smuggled into the United States, then take grueling jobs paying under minimum wage. Because of their illegal status, they hesitate to complain to authorities; the employers are rarely punished.
"The authorities think the workers are colluding with the bosses — that they're not victims because they don't complain," Lam said.
Laura Germino, who combats slave labor on farms as a leader of the Florida-based Coalition of Immokalee Workers, said federal agencies could undermine trafficking by cracking down on all types of workplace exploitation.
"You can't view trafficking in a vacuum," she said. "It takes root in industries that already have a range of labor violations — subpoverty wages, no benefits, no labor relations."
Traditionally, law enforcement agencies were unsympathetic to undocumented immigrants, regardless of their situation. However, the recent anti-trafficking initiatives have changed the equation, both for the authorities and the private groups they now rely on to win the confidence of victims.
"Federal prosecutors are not used to dealing with immigrant victims of crime from a positive perspective, so there's been a very difficult, steep learning curve," said immigration law expert Gail Pendleton "It takes time to build trust with immigrant communities. You can't just put up a sign saying 'We help trafficking victims' and expect people to come."
An estimated 40 percent of trafficking victims are under 18, most of them girls. Susan Krehbiel of the Lutheran Immigration and Refugee Service said many of these children are sexually exploited in the United States after travelling here with the consent of relatives who were told genuine opportunities awaited.
Krehbiel conducts workshops with child welfare workers who are unfamiliar with trafficking. "A lot of people thought we were going to talk about the problem overseas — they didn't realize it's a problem in their own backyard," she said.
Given Kachepa was one such young victim; as an 11-year-old orphan in his homeland of Zambia he was recruited into a boys choir that toured the United States for 18 months. Promises of education, free clothes and money for his family proved false, and the boys — constantly threatened by their handlers — were forced through an arduous concert schedule until authorities finally intervened.
Kachepa was taken in by a Colleyville, Texas, couple who became his guardians. Now 19, he obtained a T-visa and entered college in August; he also has become a spokesman on behalf of trafficking victims.
"The most important thing is constant educating of people," he said in a telephone interview. "There's help out there — but victims don't know it."
