The ban withdraws the granting of entry visas to travellers from the Muslim-majority countries of Chad, Iran, Libya, Somalia, Syria and Yemen, as well as those from North Korea and Venezuela.
President Trump first indicated that he would block Muslims from travelling to the US as he campaigned for the presidency in 2015. During his first month in office, he signed the 'Protecting the Nation From Foreign Terrorist Entry' executive order. This barred travel to the US from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen, sparking widespread condemnation and numerous legal challenges.
In the months that followed, he exempted US residents from the order, and those with "bona fide" businesses and familial interests. Iraq was later removed from the list, whilst North Korea and Venezuela were added.
Below are a handful of accounts from people affected by the executive order since it has come into full effect;
The mother and sister missing from a wedding
In April, Sanaz Karbasi, originally from Iran, and Mark Hemphill, a US citizen, were married on a pier looking out over Baltimore harbour. But the day was marred by the absence of Karbasi's mother and older sister, who were denied entry to the US from the Iranian capital of Tehran.
"This is my biggest dream since I was five years old," Elnaz Karbasi, told The Guardian "to be at my little sister's wedding". After calling the US consulate in Dubai three times a day for a month, Elnaz and her husband spent $1,400 to fly to Dubai and have their case appealed, but to no avail.
The ruined family reunion
In the days after Trump signed the executive order, footage emerged of those affected by the hastily introduced ban. Among them was Hossein Khoshbakhty, who wiped away tears as he spoke of his brother's ordeal.
Ali Vayeghan had planned for 12 years to see his son, who is a US citizen, but was detained at LAX airport for seven hours despite having a valid visa. He was then sent back to Iran. The American Civil Liberties Union of Southern California rallied around Vayeghan, and petitioned the courts to release him, according to the LA Times. Vayeghan later returned to LAX, where he was greeted by his family and the mayor of Los Angeles Eric Garcetti.
Vayeghan's niece, Marjan Vayghan, who lives in West Los Angeles, told the LA Times: "We did not think this would be a big deal — we'd pick my uncle at LAX, eat, hang out, travel. We didn't know our entire world would turn upside down."
The musicians swept up in the ban
Iranian-born indie R&B singer Sevdaliza has been based in the Netherlands since she was accepted there as a refugee in her teen years. She had planned to perform in the US, but was unable to do so following the ban. As a response, she released the song Bebin.
"In protest of the inhumane political climate, I could not rest my head in privilege. I wrote 'Bebin' in Farsi, to solidify. I stand strong with love," she wrote in a Facebook post.
Similarly, Kinan Azmeh, a Syrian clarinetist based in New York, was stuck in Beirut for a month when the travel ban was first announced after he had flown to perform alongside the world-renowned cellist Yo-Yo Ma in Hamburg, Germany. "With a single signature, someone can change your life," he told The Daily Beast.
