Wizi came to Sweden as a 15-year-old refugee from Somalia and spent two years underground before being granted asylum. His story is similar to the tales told by others fleeing conflict and instability.
"I went from Mogadishu to Nairobi to Uganda to Sudan to Libya then across the Mediterranean to Malta and, finally, to Sweden," said Wizi.
His journey began back in 2008 when he left Somalia. Friends and family had warned him about the perilous route, telling him to take special care in the Sahara sesert where so many refugees have got lost and died of thirst.
But the trip from Sudan to Libya through the Sahara went smoothly, says Wizi. The nightmare began when he came to Libya and began looking for a way to cross the Mediterranean to Europe.
Wizi, who has used false name to hide his identity, was sold from one smuggler to another. When he came to the Libyan coastal city of Misrata, he paid another smuggler to take him by boat across the sea to Europe.
The European Union recently adopted a common migration policy, but the issue continues to arouse debate ahead of European elections.
Lars Adaktusson is a Christian Democrat Party candidate for the EU. He says: "We need more practical and legal routes into Europe in order to have an effective policy."
In Sweden, the Green Party, the Left Party, the Liberal Party, the Centre Party, the Christian Democrat Party and the Pirate Party all believe that it should be possible to apply for asylum - or asylum visa - to the EU outside EU borders.
Green Party candidate, Peter Eriksson, believes that the pressure on some embassies might be too great. "It's possible that it would be too hard. But it requires more countries to take responsibility for the problem. Nothing will work if it is only Sweden and Germany that receive people . All countries must share this responsibility," he said.
