Passengers arriving into Northern Ireland may soon have to provide a negative Covid-19 test before departure.
The Stormont Executive is considering the proposal which has been submitted by the Health Minister Robin Swann.
Last week he said he had agreed "in principle" to the move but details were being worked out by officials.
People arriving from countries not on the government's travel corridors list will also still have to self-isolate for 10 days.
Stormont's first and deputy first ministers spoke to the Taoiseach Micheál Martin about the issue on Wednesday evening, it is understood.
Passengers arriving into the Republic of Ireland are subject to new rules from Saturday.
Negative tests prior to arrival are a requirement for passengers travelling from Great Britain and South Africa.
Thursday's executive meeting will also see ministers get the latest assessment of the coronavirus situation in Northern Ireland.
Northern Ireland is in the third week of a six-week lockdown to curb the spread of Covid-19.
