The U.S. Supreme Court ruled in favor of President Donald Trump Monday, allowing a limited version of his travel ban on six majority Muslim countries to come into effect.

The announcement reversed several decisions from lower federal courts that had suspended the ban earlier this year, arguing it was discriminatory. Judge Derrick K. Watson of Honolulu wrote that the order was “issued with a purpose to disfavor a particular religion, in spite of its stated, religiously neutral purpose,” when he ruled against the ban in March.

Travelers from Iran, Libya, Somalia, Sudan, Syria and Yemen will be affected by Trump's executive order, and the president promised to put the ban into effect 72 hours after the Supreme Court decision, the Associated Press reported.

The order suspends any new visa processing for 90 days, though people with existing visas from those countries should still be able to travel to the U.S. It also halted the U.S. refugee program with those countries for 120 days.

The highest court did include one category of exception, saying that citizens from those countries who have a "credible claim of a bona fide relationship with a person or entity in the United States,” would be protected, according to the same AP report.

The Supreme Court agreed to take the case and will hear arguments from both sides when it reconvenes in October.

Trump first issued the executive order in March as an updated version of a previous order that had caused chaos and widespread protests at airports across the country.

What it means for travelers

With the executive order set to take effect in the coming days, travelers should brace for potential delays and confusion at the airport. Adding an extra hour or even two to travel time at the airport, especially for those traveling internationally, is always a good idea.

While the order should not affect them, visa-holders or permanent residents from any of the six countries involved should make sure to have their proper documentation with them at all times and be prepared for potential added screening at the airport.
