Most applicants for US visas will have to submit their social media details under newly adopted rules.

The US State Department regulations say people will have to submit social media names and five years’ worth of email addresses and phone numbers.

Authorities estimated the proposal would affect 14.7 million people annually when proposed last year, the BBC reported.

Certain diplomatic and official visa applicants will be exempt from the new measures.

However, 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, 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.

But now applicants will have to give up their account names on a list of social media platforms, and also volunteer the details of their accounts on any sites not listed.

The plans emerged as president Donald Trump was due to land at Stansted for a three-day state visit to the UK.
