The US administration under President Donald Trump is reportedly considering expanding its travel ban to include citizens from 36 additional countries, news agency Reuters reported.This development comes after Trump’s recent executive order banned the entry from 12 countries, citing national security concerns and insufficient cooperation with US vetting standards.This move is part of a wider immigration crackdown announced earlier this year at the start of Trump’s second term. Measures already introduced include deporting hundreds of Venezuelans suspected of gang involvement and restricting some international students’ access to US universities.Also read | What to know about Trump’s new travel ban on 12 countriesThe internal cable, signed by US Secretary of State Marco Rubio, outlines a number of concerns. “The Department has identified 36 countries of concern that might be recommended for full or partial suspension of entry if they do not meet established benchmarks and requirements within 60 days,” the message stated, as reported by Reuters.Concerns listed include the lack of cooperation from some governments in producing valid identity documents or ensuring the security of their passports.
