SANTA FE, N.M. (AP) — Alejandro Altamirano has called New Mexico home for a dozen years. It's where his two daughters, born in the United States, are being raised.

But the 36-year-old dairy farm worker from Durango, Mexico, fears he'll be forced into the shadows if he loses his driver's license.

New Mexico, for years, was out in front on handing out driver's licenses to people suspected of being in the country illegally. Now, legislation to stop the state's practice is gaining traction despite a trend sweeping through several states to offer driving privileges to everyone regardless of their status.

Fresh off a political power shift, the Republican-led House of Representatives is poised to pass a measure repealing a 2003 law that made New Mexico one of the first states to offer licenses to immigrants regardless of status. Senate Democrats say they will fight the legislation.

The legislation has sparked a fight in the state, which the nation's highest percentage of Latinos and the only Latina governor — a Republican who favors repealing the law.

Proponents of the bill say polling shows most New Mexicans want to repeal the law. They argue doing so would help prevent fraud and bring the state into compliance with federal identification requirements.

California this year began issuing driver's licenses to immigrants who are in the country illegally, bringing the number of states that do so to 10. California expects 1.4 million people to apply for the licenses in the next three years.

"It's a product of many years and the need for driver's licenses," said Tanya Broder, senior staff attorney with the National Immigration Law Center in Los Angeles. "From a policy perspective, it made sense that all the drivers were tested and licensed and insured and accountable for their driving records."

Those who want to keep New Mexico's law the way it is argue working families stand to get hurt. The opposition argues New Mexico has become a haven for those seeking to fraudulently obtain driver's licenses.

"These fraud operations involve the trafficking of humans to our state for the purpose of committing crimes; and with no intention to live here, they snatch up our license to take elsewhere, to places unknown and for purposes unknown," said Mike Lonergan, spokesman for Gov. Susana Martinez.

The governor and others have said the original law has failed to drive down the rate of uninsured motorists as intended.

Repeal supporters point to a 2014 Albuquerque Journal poll showing 75 percent in the state were against the law. Detractors point to other polls, saying a majority of Hispanic residents in New Mexico support giving licenses to people regardless of status.

Meanwhile, Altamirano waits.

He hopes he can keep his driver's license because it could mean losing his job, his home and everything he has worked toward.

"I will live with more fear, and especially more fear of police when I drive," he said.
