London said that this is in addition to established requirements to obtain a visa to travel to the UK for the purpose of work, study and settlement. “There will be a six-week transition period until April 23, 2025, during which time visitors who booked their travel and obtained an ETA (electronic travel authorisations) before the changes can still enter the UK without a visa. There is also a transition period for passengers who are transiting via the UK to an onward destination,” London said in its statement.
