First lady Melania Trump's parents have become USA citizens after taking the citizenship oath during a ceremony on Thursday. To apply for US citizenship, a person must have a green card for at least five years, plus meet the character, residency, and civic knowledge requirements.
They came and went from the ceremony at a Manhattan federal building flanked by Homeland Security police.

"This golden experiment, these doors that are in America, remain hinged open to lovely people as they have today", Wildes said.
They had been living in the U.S.as permanent residents.
Melania Trump, who has been vacationing with her husband in Bedminster, New Jersey, did not accompany her parents. Trump has sought to eliminate family-based sponsorship, which he calls "chain migration", and replace it with merit-based citizenship programs. Trump has advocated a "merit-based" system, but has not proposed any method of admitting immigrants to the United States to replace those categories.
Experts estimate those measures would cut legal immigration into the US almost in half.
The Knavses' citizenship ceremony was kept hush-hush at the Jacob K. Javits Federal Building.
The Knavses are from Slovenia, but now divide their time between New York City, Palm Beach, and Washington, D.C., where they stay with the Trumps in the White House.
The first lady was named Melanija Knavs when she was born in Slovenia but later changed her name to Melania Knauss when she began her modeling career. They married in 2005.
Trump hasn't commented or tweeted about his in-laws' newfound citizenship.
Mr Knavs is 74, two years older than President Donald Trump.
