A story idea for journalists covering the Africa Cup of Nations

In Equatorial Guinea there are many foreign West African immigrants, and lots of them are not in the country legally.  During the Africa Cup of Nations more West Africans will enter the country on tourists visas, purportedly to see the games, but then overstay their visa.  (People think, wrongly, that there are lots of jobs in Malabo because of the oil.)  There is a fear among those who have been in the country for a while that after the tournament the government will conduct raids and crack down on illegal immigration.  The harassment of foreign West Africans is already awful.  I can’t imagine what it would mean for it to be worse.
