The US government announced a new rule on Friday requiring foreigners to leave the US and apply for a green card from their home countries.
The announcement comes as the latest move in a series of attempts the Trump administration has already taken to restrict and limit entry for people from dozens of countries.
What did the USCIS say about the new rule?
"From now on, an alien who is in the US temporarily and wants a green card must return to their home country to apply, except in extraordinary circumstances," US Citizenship and Immigration Services (USCIS) spokesman Zach Kahler said in a statement.
"Nonimmigrants, like students, temporary workers, or people on tourist visas, come to the US for a short time and for a specific purpose," Kahler said, adding, "Our system is designed for them to leave when their visit is over."
