Under the newly adopted rule, nearly all applicants for United States visas will now have to submit their social media details.

According to the State Department regulations, people will have to submit social media names and five years’ worth of email addresses and phone numbers.

Authorities had estimated that the proposal would affect 14.7 million people annually, when proposed last year,

However, certain diplomatic and official visa applicants will be exempted from the stringent new measures.

But people travelling to the US to work or to study will have to hand over their information.

“We are constantly working to find mechanisms to improve our screening processes to protect US citizens, while supporting legitimate travel to the United States,” the department reportedly said.

Previously, according to BBC report, only applicants who needed additional vetting, such as people who had been to parts of the world controlled by terrorist groups, would need to hand over this data.

Anyone who lies about their social media use could face “serious immigration consequences”, according to an official who spoke to The Hill.

The Trump administration first proposed the rules in March 2018.

At the time, the American Civil Liberties Union – a civil rights group – said there is “no evidence that such social media monitoring is effective or fair”, and said it would cause people to self-censor themselves online.

US President Donald Trump made cracking down on immigration a key plank of his election campaign in 2016.

On Friday Mr Trump vowed to impose gradually rising tariffs on Mexico unless the country curbed illegal immigration at the US southern border.
