"These doors that are in America remain hinged open to handsome people as they have today". Politico said the parents were "expected to become more familiar figures around the White House, helping care for Barron, though they don't plan to relocate full time to Washington".
"This golden experiment, these doors that are in America, remain hinged open to lovely people as they have today", Wildes said after the ceremony.
The pair are close with the president and Melania Trump, and are regularly seen traveling with the first family.
Her spokeswoman, Stephanie Grisham, declined to comment.
It is not infrequently the site of protests, but on Thursday, things were quiet as the First Lady's parents came and went.
Along with targeting illegal immigration, Donald Trump has proposed sharply curbing legal immigration. While the president never names Saipov, who obtained his green card through the equally maligned diversity lottery, which grants visas to people from countries that have had fewer immigrants, he has been known to detail the attack. Experts estimate that could cut overall immigration to the United States by 40% to 50%, if those green cards are not reallocated to another category.
Asked if the Knavses had obtained citizenship through "chain migration", Wildes, said, "I suppose".
Under immigration statutes, the Knavses would have needed to have their green cards for at least five years in order to apply for citizenship, along with fulfilling character, residency and civic knowledge requirements, it said.
The Knavses' citizenship ceremony was kept hush-hush around the Jacob K Javits Federal Building. Now that the couple are USA citizens, it's important to note the president's hypocrisy when it comes to immigration policies. New citizens are normally minted on Fridays, they said, and often the ceremonies are held at the federal courthouse across the street.
The Knavses, both in their 70s, raised Melania Trump in Sevnica, a Slovenian town of around 4,500 people.
Viktor, 74, is two years older than President Trump. They married in 2005. Trump has advocated a "merit-based" system, but has not proposed any method of admitting immigrants to the USA to replace those categories.
