Current and former U.S. immigration officials told CBS News the memo published Friday would likely have wide-ranging implications, forcing groups like students, tourists and other temporary visa holders, as well as those who entered legally but overstayed their visas, to leave the country before trying to obtain a green card through sponsorships filed by U.S. citizen spouses or employers.

In an emailed statement to the Associated Press USCIS said people who provide an “economic benefit” or “national interest” could likely stay in the U.S. while others would have to go abroad to apply.
