Officials in the United States have revealed plans to tighten travel restrictions for visitors using the visa waiver programme.
Approximately 20 million people from 38 countries presently enter America each year under the visa waiver programme, which allows travel without needing full visas.
The scheme has come under increased scrutiny since terrorist attacks in Paris last month; with lawmakers questioning with militants could get into the US.
Under proposed changes presently submitted to Congress, all countries enrolled in the scheme would be asked to issue “e-passports”.
Registrations for these new documents would come under greater scrutiny from US agencies.
Travellers would also be screened to see if they had travelled to militant-held areas.
The Department of Homeland Security will also ask Congress for additional powers, including increase fines for airlines that fail to verify passport data.
