WASHINGTON DC: US President Donald Trump's ban on refugees and travelers from six mainly Muslim countries went into effect, after a Supreme Court decision allowed it to go forward following a five-month battle with rights groups.
The Trump administration says the temporary ban is necessary to block terrorists from entering the country, but immigrant advocates charge that it illegally singles out Muslims.
The 90-day ban on visitors from Iran, Libya, Somalia, Sudan, Syria and Yemen, and a 120-day ban on refugees, will allow exceptions for people with "close family relationships"
in the United States.
But activists said the government has defined that too narrowly, excluding relationships with grandparents and grandchildren, aunts and uncles and others.
And many were concerned about a possibly chaotic rollout of enforcement of the ban, like that in January when it was first announced.
Immigration rights activists and lawyers were waiting to help arrivals at New York's John F. Kennedy International Airport and other airports to be sure those from the six countries with valid US visas were allowed in after the ban went into effect at 8 pm Thursday Eastern time (0000 GMT Friday).
The Department of Homeland Security, which was heavily criticised for mishandling many arrivals when the ban was first attempted in January, promised a smooth rollout this time.
It stressed that anyone with a valid visa issued before the ban begins would still be admitted, and that all authorised refugees booked for travel before July 6 will also be allowed.
"We expect business as usual at the ports of entry starting at 8 pm tonight," said a DHS official. "Our people are well prepared for this."
The Trump administration insists the ban was necessary to protect the country from terror threats, and to give immigration authorities more time to tighten vetting of travelers and refugees.
"As recent events have shown, we are living in a very dangerous time, and the US government needs every available tool to prevent terrorists from entering the country and committing acts of bloodshed and violence," a senior administration official told reporters Thursday.
But implementing it, even with exceptions, was also claimed as a political victory by Trump, after federal appeals courts twice blocked his order saying it violated constitutional protections of religion and overshot his own presidential powers.
Immigrant rights groups and Democrats in Congress continued to label Trump's order "illegal" and said the exemptions provided in a Supreme Court ruling on Monday remained unfair.
According to guidelines issued by the State Department, people with "close family relationships" would be exempt from the ban. It defined that to include parents, spouses, children, sons- and daughters-in-law, siblings and step- and half-siblings.
But "close family" does not include grandparents, grandchildren, aunts, uncles, nieces, nephews, cousins, brothers-in-laws and sisters-in-law, fiances and any other "extended" family members, the guidelines say.
People with formal relationships with a US entity -- who have for instance been offered a job or been accepted to study or lecture at a university -- will also qualify for visas during the ban. But a hotel reservation, even if already paid for, does not qualify.
Even as travel officials across the US were making final preparations for putting the ban into place, opponents were preparing new legal maneuvers.
Late Thursday, Hawaii asked federal district Judge Derrick Watson to clarify the scope of the travel and refugee bans in the Pacific island state -- and who, specifically, the ban refers to when stating that only an immigrant's close family members can travel to the US.
"In Hawaii, 'close family' includes many of the people that the federal government decided on its own to exclude from that definition. Unfortunately, this severely limited definition may be in violation of the Supreme Court ruling,"
Attorney General Douglas Chin, said in a statement.
Democratic legislator Bennie Thompson blasted the government for a "lack of preparation and transparency" in putting the ban into place.
