The pair congratulated the new citizens and talked about the important contributions of immigrants to Texas and the United States.

“Texas has been the land of immigrants. Our state is a place where people come year after year to build a better life,” said former First Lady Laura Bush.

“You paid America the high tribute of aspiring to live here, leaving behind familiar ways and places and accepting a process that everyone knows is not easy,” said former President George W. Bush.

The Bush Institute’s immigration program says it advocates for smart, skills-based immigration reform.

This was the second naturalization ceremony at the Bush Institute.

“As president, I worked hard on comprehensive immigration reform, and I regret that our efforts came up short,” Mr. Bush said. “Today, emotions can cloud the issue. But here at the Bush center, we are clear-eyed about the need to enforce our borders and protect our homeland, and about the critical contributions immigrants make to our prosperity and to our way of life.”
