A professional athlete who’d previously been granted a visa for sportsmen with extraordinary abilities. A student about to start a master’s degree. Three friends who planned a short trip to Southern California are now sitting in detention centers.

All of them were flying to or from San Francisco International Airport when they were detained by immigration agents, part of a new front in the Trump administration’s mass deportation campaign. At least 11 Bay Area residents have been ensnared in the crackdown in the past three weeks, according to immigration attorneys, relatives and witnesses.

Bay Area politicians, immigration attorneys and civil rights activists are now warning immigrants with unresolved immigration issues to avoid traveling through airports if possible.

U.S. Immigration and Customs Enforcement is now targeting foreign citizens with expired travel visas for detention, even when they have U.S. spouses, no criminal records, no removal order against them and have pending applications for legal immigration statuses — a group that federal immigration agents have not historically focused on detaining.

“The manner in which ICE has detained them is what we find problematic,” Shamieh said. “That they’ve done this without a pre-deprivation hearing.”

Five of his clients have been detained at airports in Los Angeles, San Francisco and Phoenix in the past two weeks. Four of those had pending asylum applications, which generally provides individuals temporary legal authorization to remain in the country and protection from deportation until a decision is made. The fifth had pending visa applications, he said. None had criminal records, he said.

“Because of this expansion, it’s not safe for people with uncertain immigration status to fly right now, including for anyone currently in the process of changing their status,” state Sen.

The New York Times reported Tuesday that immigration agents in plain clothes have been picking up people with expired visas across 15 airports, including San Francisco. At least 27 arrests across nine states, including California, targeted those with expired visas, ABC News reported. Before the most recent detentions, ICE agents in airports mainly targeted those with judge-issued removal orders or administrative warrants.

San Francisco-based immigration attorney Kyra Lilien said her firm is advising clients to avoid air travel if they have an ongoing asylum case, pending green card application or any other non-permanent status that may be in transition or pending approval.

Lilien, a former immigration judge who lost her job under Trump, said ICE agents’ recent actions are worrisome for anyone with a nonpermanent status, including those who have valid work visas.

People with expired visas span a broad category that covers hundreds of thousands of people, including those married to U.S. citizens, skilled workers and people with valid work permits issued by the federal government while awaiting green cards or visa extensions. They lack permanent legal status but, in most cases, are actively trying to obtain it.
