Of the estimated 11 million unauthorized immigrants in the United States, some 80 per cent are from Mexico or elsewhere in Latin America. But the second largest group -- 1.5 million -- are from Asia, according to government figures and researchers.
The majority hail from China, India, the Philippines and South Korea, representing the fastest-growing segments of unauthorized immigrants in the United States since 2000, according to the Pew Research Center and the Migration Policy Institute.
And yet Asians have often been overlooked in the current debate over illegal immigration, which has mainly been cast by the Trump administration as a Mexican issue that can be tackled by building a wall along the US-Mexico border.
"Asians in the United States have not received the same sort of focus as people from Mexico and Latin America," said Stephen Yale-Loehr, an immigration lawyer and professor at Cornell Law School.

"It's all fear-related, from people with or without status, to those with a visa or in the process of applying for citizenship."
He said the anxiety is such that in one instance a Korean woman in Los Angeles who was domestically abused refused to go to the police for fear she and her family would be deported.
And unlike immigrants from Mexico or Central America, they usually don't come from a poor background and have immigration petitions in the pipeline.
Bang said that many undocumented Asians, especially Koreans, have taken advantage of Obama-era executive policies on Deferred Action for Childhood Arrivals (DACA) and Deferred Action for Parents of Americans and Lawful Permanent Residents (DAPA).
These defer deportation for unauthorized immigrants who grew up in the United States and for parents of American citizens or legal residents.
The concern now, however, is that these programs face an uncertain future under the Trump administration.
