Qatar has transformed its infrastructure in the run up to the World Cup, which starts on Sunday. Five million people from South Asia have been employed on building projects, including from Nepal - where families have told the BBC safety failures led to the death of their loved ones.
In the early hours of 10 November, Qatar airlines flight QR 644 touched down at Nepal's Kathmandu airport.
Among the cargo unloaded from the plane was a large white wooden box. "Human Remains of late Umesh Kumar Yadav, 32 years male, Nepali" was written on the outside.
In Golbazar, 250km (155 miles) south-east of Kathmandu, his father ties up his buffalo outside his brick house. He lives in one of the poorest districts of one of the poorest nations in the world, where opportunity is scarce.
When his son Umesh was offered the chance to go and work in Qatar, one of the world's richest countries, Laxman Yadav sold some buffalo to pay $1,500 (£1,250) to an employment agent who promised to arrange a job.

It's common for agents to visit impoverished areas not just in Nepal, but in Bangladesh and India, offering young men a lucrative job overseas, in exchange for large sums of money to secure them a visa.
The workers are often passed from contract to contract, making it hard for the families to know where their relatives are working, and for whom.

A two-hour drive away in the district of Dhanusha is Krishna Mandal's house. His father Sitesh left to work in Qatar four years ago.
Sometimes Sitesh sent his son selfies while at work. "He told me he worked on water tanks, but didn't tell us too much about what he was doing," says Krishna.
Sitesh was due to return for a visit on 12 October. But just days before, Krishna got a phone call telling him his father had been killed in an accident.
A family friend said Sitesh was been working on sewage pipes, seven feet below ground in the capital Doha, when a heavy mound of earth fell onto him. His death certificate said he suffered "multiple blunt injuries due to solid object impact".
Krishna says he hasn't received a single phone call from his father's employer, or an offer of compensation. The BBC contacted the company Sitesh worked for to get a comment, but they didn't respond.
From Golbazar, Laxman didn't know too much about his son's life in Qatar - he does not own a smartphone and couldn't follow the daily updates Umesh used to post on TikTok.
In his videos, he could be seen dancing in front of Qatar's glitzy skyline or in his dorm-style accommodation with other migrant workers
On 26 October, Umesh posted a video of himself dancing at night in front of some skyscrapers running adverts for the upcoming World Cup.
It was the last post he'd ever make.
