President Donald Trump has suspended the US green card lottery scheme in the wake of a mass shooting at Brown University last week in which two people were killed.
The suspect, a Portuguese man who was found dead on Thursday, entered the country through the diversity lottery immigrant visa programme (DV1) in 2017 and was granted a green card.
The programme makes up to 50,000 visas available each year through a random selection process among entries from countries with low rates of immigration to the US.
