Lawyers have set up shop at JFK Airport on Thursday night to help those impacted by President Trump's travel ban, which went back into effect in a limited form in the evening.

Things appeared to be running normal at the airport around 11 p.m., but a small team of attorneys were present inside a terminal, ready to act if any travelers might need assistance because officials are detaining or questioning them.

The attorneys, who the New York Immigration Coalition organized, are ready to provide representation.

The travel ban took effect 8 p.m.

Visa applicants and refugees from six Muslim-majority countries — Syria, Sudan, Somalia, Libya, Iran and Yemen — must now prove a personal tie to someone already in the United States, under the rules the partial travel ban has established.

The State Department defines a close family member as a parent, child, spouse, sibling, adult son or daughter, or son or daughter-in-law.

Business and professional ties are also accepted.

But the State Department says they must be "formal, documented and formed in the ordinary course rather than for the purpose of evading" the president's executive order.

The ban takes effect just days after the Supreme Court partially restored Trump's amended executive order.

The high court will hear arguments in the case this fall.

Jan. 28 — shortly after Trump signed the original travel ban executive order which barred visitors from the six countries and Iraq — thousands of people descended on the airport to protest the ban and some travelers being detained.

An attorney at JFK Airport told NY1 they do not expect many overnight flights to enter the airport with travelers who the ban would affect.
