Dhanusha, Nepal (CNN)At Kathmandu's Tribhuvan International Airport, hundreds of migrant workers line up daily at the immigration counters, clutching newly printed passports and boarding passes. Many of them, though, are clueless as to where they're headed. 

As a frequent traveler to the country, I've been approached many times by these men, asking me to help fill out their departure forms. 

Usually, when I ask what country they're traveling to, I get the same answer: "I'm not sure." 

They seem weary and lost but still hopeful that they can make their lives better. 

This time, however, I'm at the airport to follow up on the repatriation of the most unfortunate of these migrant workers -- far too many of them make the return journey in caskets. 

Almost every day, the remains of three or four workers arrive back in Nepal from the Middle East, according to Bhola Prasad Siwakoti, the secretary of the Nepalese Ministry of Labor and Manpower. Every other day, at least one dead body arrives from Qatar, he said. 

"Nepali migrant workers have the lowest per capita income in Qatar," says Suryanath Mishra, who served as ambassador to Qatar from 2007 to 2012. "They get exploited the most out of all the migrant workers." 

He cites lack of education and technical skills as the main causes. 

We are waiting for the body of Kishun Das, who left Nepal for Qatar only eight months ago. The 38-year old was his family's breadwinner and the father of five children. 

His younger brother, Bishun, is at the airport to receive the body. He also works in Qatar and is in Nepal on leave. I ask him why he's alone.
