Saudi Arabia, a close ally of the United States, is not known for surprises. But in a sudden shift in power, the 31-year-old son of the 81-year-old Saudi king moved one step closer to the throne on Wednesday.

King Salman bin Abdul-Aziz Al Saud promoted Mohammed bin Salman, his youngest son, to crown prince. At the same time, the king ended the career of his nephew, 57-year-old Mohammed bin Nayef, the previous crown prince, who had served as interior minister since 2015.

Groups that resettle refugees in the United States are facing uncertainty, disarray and possible deep budget cuts as a result of President Trump's executive order on immigration, even after a California appeals court has temporarily halted enforcement.

Here's why:

The federal appeals court that blocked the president's travel ban on people from seven majority-Muslim nations did not directly rule out two provisions in the executive order. Refugee resettlement agencies are scrambling to figure out what they will do if those provisions survive.

The Trump administration says it is suspending all refugee admissions to the United States until it can come up with a plan for "extreme vetting."

So what could that mean?

Refugees are already subjected to multiple interviews and a security vetting by nine U.S. law enforcement, intelligence and security agencies that check their backgrounds, social media activity and the reasons they fled their countries. The process usually takes 18 months or more, according to resettlement agencies.

When Almothana Alhamoud, a 31-year-old Syrian data analyst, arrived in Chicago two years ago after fleeing the Syrian war, he jumped at his first job offer, a nightshift cashier at a convenience store.

"When I came over here I just want to find anything to survive," he says over dinner with his family in Chicago. His parents and two sisters fled Damascus six months after he did. The family has applied for asylum in the U.S.
