Tons of immigrants flock to South Africa from across the border each year. This story refering to Mozambican repatriation caught my eye:

“Orlando Cossa, head of the immigration services at Ressano Garcia told the daily Noticias that at least 8017 illegal Mozambicans were repatriated through that border post in March and in February, at least 3577 illegal Mozambicans were repatriated through the same border post.

Cossa said in March the Mozambican immigration officials also deported 16 South Africans who were living illegally in Mozambique, a decrease from 20 who were deported in February.

“We continue to have illegal entries through the porous border post from both countries by people who sneak through illegal points,” said Cossa.

While a lot of Mozambicans entered legally into South Africa, they overstayed their 30 days, which are allowed under the visa waiver agreement.

The terms of the visa waiver agreement allows thousands of Mozambicans who shop and do business in South Africa to enter without visas.

The visa waiver also allows citizens of either country to stay in the other country for up to 30 days without a visa.

Mozambique also has visa waiver agreements with Namibia, Botswana, Malawi, Namibia, Swaziland, Zambia and Zimbabwe.

Immigrations officials have said in recent media reports that the visa waiver has resulted in an increase in the movement of people at the Ressano Garcia/Lebombo border post.”
