The Supreme Court has decided to allow parts of President Donald Trump’s travel ban take effect. The court will also hear arguments on the validity of the ban, according to CNN.

The concerning part of the ban that will affect countless lives is a banning foreigners who can’t prove they have a “bona fide relationship with any person or entity in the United States.” This decision goes completely against the narrative many proud citizens place on “the American dream.” If it becomes permanent, the travel ban will keep foreigners from a very specific group of countries from coming to the United States to seek the better lives they’ve been promised for decades.

Meanwhile, Trump sees this decision as a clear victory in his attempts to place the U.S. in a cultural bubble.

“As President, I cannot allow people into our country who want to do us harm,” he added in a statement. “I want people who can love the United States and all of its citizens, and who will be hardworking and productive.”

Another clear issue is the subjectivity in the decision. What determines a “bona fide relationship”? Will these standards be the same across the country? Probably not.

“That’s going to be an extreme headache. Think about how the people at the border, at airports are going to make that decision,” said Page Pate, CNN legal analyst. “Who is going to make this decision? If we leave it to the folks on the front line, that’s just going to lead to more litigation.”

The ban could take effect within as soon as 72 hours from its announcement on Monday, so there’s no telling when the headaches will start or when they’ll stop.
