San Diego, January 1: President Donald Trump on Thursday extended pandemic-related bans on green cards and work visas to large groups of applicants through March 31, while a federal appeals court sided with him on a rule that requires new immigrants to have their own health insurance.

The twin developments on the final day of 2020 encapsulated how Trump has made US immigration policy more restrictive without support from Congress. President-elect Joe Biden has promised to undo many of Trump's actions but it is unclear how quickly and even to what extent.

Federal judges have limited the impact of the pandemic-related visa bans, which were set to expire Thursday. Biden, who is now forced to decide when and whether to lift them after taking office January 20, doesn't specifically address the issue in his immigration platform.

Biden also doesn't directly address the health-insurance requirement in his platform and a lawyer who sued over the policy on Thursday urged him to immediately rescind it."

In April, Trump imposed a ban on green cards issued abroad that largely targets family members of people already in the United States.

After a surprisingly chilly reception from immigration hawks, the administration went much further in June by adding H-1B visas, which are widely used by American and Indian technology company workers and their families; H-2B visas for nonagricultural seasonal workers; J-1 visas for cultural exchanges; and L-1 visas for managers and other key employees of multinational corporations.

Trump said the measures would protect American jobs in a pandemic-wrecked economy, while business groups said they would hamper a recovery.

"The effects of COVID-19 on the United States labour market and on the health of American communities is a matter of ongoing national concern," Trump's proclamation read, highlighting the growing number of cases and states' restrictions on businesses.

By contrast, the administration's edict to immediately expel asylum-seekers and others who cross the border illegally from Mexico was justified on grounds of containing the coronavirus, though reporting by The Associated Press and others found that government scientists saw no evidence for it. A temporary ban on non-essential travel across the Mexican and Canadian borders was also done for public health.

In October, a federal judge in San Francisco ruled that the work-visa ban could not be enforced against groups that sued and their members, who represent much of the US economy: the US Chamber of Commerce, the National Association of Manufacturers, the National Retail Federation, technology industry group TechNet and Intrax Inc., which manages cultural exchange programs.

In December, a federal judge in Oakland, California, prevented the green-card ban from taking effect against families of 181 US citizens and legal residents who sued.

In its ruling issued on Thursday, a 9th Circuit Court of Appeals panel voted 2-1 to clear the way for Trump's requirement that immigrants have health insurance. New immigrants must demonstrate they can obtain coverage within 30 days and pay their medical expenses. A federal judge blocked the rule from taking effect almost immediately after it was announced in October 2019.

Judge Daniel P Collins, a Trump appointee, wrote that the president acted within his authority, relying largely on the Supreme Court's ruling that upheld Trump's travel ban on several predominantly Muslim countries. He was joined by Judge Jay Bybee, who was appointed by President George W. Bush.

Judge A Wallace Tashima, who was appointed by President Bill Clinton, dissented, calling the policy "a major overhaul of this nations immigration laws without the input of Congress - a sweeping and unprecedented exercise of unilateral executive power".

Esther Sung, an attorney for Justice Action Center, an advocacy group that sued to block the rule, said she was disappointed. The ruling "makes clear that the Biden administration must move swiftly to rescind all of President Trump's xenophobic presidential proclamations, including this health care ban," she said.

The Justice Department did not immediately respond to a message seeking comment.
