If Mustafa had known what it would be like living in a refugee camp in the Greek capital, he would never have left Syria. Four months of living in a broken tent by Athens' Pireaus harbour, waiting for his asylum claim to be processed has caused Mustafa to bitterly regret his decision to leave Aleppo. "Anywhere. Anything is better than this," he said as a tear trickled down his cheek.

Only 38, Mustafa, who like many asylum seekers declined to give his full name, looks much older - as does his wife Nadia, 37, who sits beside him, sweaty and squashed in their small tent. Outside the temperature rises to more than 35 degrees Celsius.

The couple left most of their family behind in Syria. "We didn't think we'd be here long but we've yet to have our first (asylum) interview," Mustafa told the Thomson Reuters Foundation.

"They've delayed it over and over again. At this rate we'll be here for years. Sometimes, I just want to take my wife's hand and jump into the sea."

Since 2015, Greece has been the main entry point into Europe for migrants fleeing conflict and poverty in the Middle East and beyond.

To receive asylum in Europe, migrants in Greece must go through a rigorous process through EASO, the European Asylum Support Office. This entails a minimum of two interviews in Greece, spread over several weeks or months, and then at least two additional interviews in their country of relocation.

"The time it takes for a relocation request to go through in Greece really depends on the member state in question. Some are relatively fast and some are not," said Iota Peristeri, who works at the Greek asylum service. "You could be lucky and you're only in Greece for three months or so, or it could take much longer," Peristeri told the Thomson Reuters Foundation.

The whole process can take months if not years. "The relocation process is so slow. I think life would be easier back in Syria," said Maha, 38, who left Aleppo with her three children in February after her husband died of a stroke.

Maha spent time in two refugee camps - one on the Greek-Macedonian border, the other by Piraeus port - before ending up in Athens' Eleonas camp, which hosts about 1,500 people. Although she registered her and her family as refugees with EASO in March, they are yet to have their first interview.

"Being at Eleonas camp is the hardest part of my journey so far. I just want them to hurry up or at the very least send us back to Syria," Maha said. "The food here is inedible but we have no choice but to eat it."

When migrants arriving on Greek islands like Samos or Lesbos get the call for their first asylum interview, they must pay for a ferry to Athens. The journey is often very expensive for families who have spent their life savings getting to Europe.

These asylum seekers are meant to be provided with accommodation in Athens but this did not happen for Damascus-born Nama Abdullah, 28, and her three children who live in Kara Tepe, a refugee camp on Lesbos. In May, Abdullah was told she and her family had an interview in Athens but unable to afford the 178 euro ($200) journey to get there, she sought financial help from other refugees. She said she received no help with accommodation. "I couldn't afford to rent a hotel for the night and all the camps in Athens sent us away," Abdullah said. "Nobody helped us, no volunteers, nobody."

Altogether, Abdullah and her children spent two nights in Athens, the time it took her to raise the money to sail back to Lesbos. Again, other refugees funded her journey.

"People are so desperate here, they'll really do anything," said Safi, a former NATO employee and translator. "Everyone is depressed here, myself included. Nobody ever feels good."
