(WASHINGTON) — Police have received reports that two of the Burundi teenagers missing after an international robotics competition were seen crossing the border into Canada.
A search for all the teens is ongoing, but police have no indication of foul play in their disappearance, Metropolitan Police spokeswoman Aquita Brown said.
The teens seen crossing into Canada were 16-year-old Don Ingabire and 17-year-old Audrey Mwamikazi, Brown said.
There was no official indication Thursday that any of the teens were trying to avoid returning to their homes in Africa, but a leader in the Burundian community in the U.S. suggested that they may be intending to seek asylum. Immigration attorneys said an asylum application could take years to sort out.
Police tweeted missing person fliers Wednesday asking for help finding the teens, who had last been seen at the FIRST Global Challenge around the time of Tuesday’s final matches. The missing team members include two 17-year-old girls and four males ranging in age from 16 to 18.
The competition, designed to encourage youths to pursue careers in math and science, attracted teams of teenagers from more than 150 nations.
A squad of girls from Afghanistan drew the most attention after they were twice rejected for U.S. visas and President Donald Trump intervened.
Competition organizers learned Tuesday night that the team’s mentor couldn’t find the six students who participated in the competition and organization President FIRST Global President Joe Sestak made the initial call to the police, according to a FIRST Global Challenge statement.
“Security of the students is of paramount importance to FIRST Global,” organizers said, noting that they ensure students get to their dormitories after the competition by providing safe transportation to students staying at Trinity Washington University. The students “are always to be under close supervision of their adult mentor and are advised not to leave the premises unaccompanied by the mentor.”
The mentor said the teens traveled from Burundi for the competition and have one-year visas, according to police reports. The mentor said they disappeared after the competition, but he doesn’t know where they went. The reports say police tried to contact one missing teen’s uncle but got no response.
The competition’s webpage about Team Burundi shows the six team members posing with a flag and says team members were selected from schools in Bujumbura, the capital city. The team’s slogan in Kirundi is “Ugushaka Nugushobora,” which translates roughly to “where there is a will, there is a way.”
Police tweeted images of the teens Wednesday, saying they are looking for 17-year-old girls, Mwamikazi and Nice Munezero; Richard Irakoze and Aristide Irambona, both 18; Kevin Sabumukiza, 17; and Ingabire, 16.
Hassan Ahmad, an immigration lawyer in northern Virginia not involved in the situation, said that if the teens make an asylum application, then Immigration and Customs Enforcement could seek to detain the teens pending removal proceedings. The teens would be eligible to seek bond and stay in the country while they await their hearing. It can take years to have a court hearing scheduled. And even if ICE declines to seek detention, it can take several years for applicants to have their formal interview to determine whether they are eligible for asylum.
Oscar Niyiragira, chairman of the United Burundian-American Community Association Inc., was not at all surprised to hear that some of the teens were heading to Canada. He had no direct knowledge of their situation, but assumed they were seeking asylum, and many in the community feel the odds are better in Canada, especially now that the Trump administration has taken a harsh stance on immigration.
He called the teens’ departure disappointing. He said that economic impoverishment, rather than political persecution, is the driving force in most people’s decision to seek asylum from Burundi, and he said it unfairly tarnishes Burundi’s reputation when people flee and exaggerate the fears of political violence.
“Now I’m not saying the government does not commit some crimes. They do,” said Niyiragira, who lives in Louisville, Kentucky. But the situation in Burundi is not nearly as bad as it was in waves of violence in the ’70s and the ’90s, he said.
Burundi, an East African nation of about 10 million people who speak the local Kirundi language and French, has faced sporadic violence in recent years.
Burundi’s government had no immediate comment Thursday.
Nkurunziza is visiting neighboring Tanzania, home to tens of thousands of Burundian refugees who have fled deadly political violence. Hundreds of people have been killed, according to the United Nations, and rights groups accuse Burundi’s security forces of abuses including killings and disappearances. Burundi’s government often dismisses the allegations, saying they are based on false information supplied by the regime’s opponents.
