Orphan children kept from foster families by Donald Trump’s travel ban

But Rooney’s family is leaving the sign blank, for now. She and her husband, Todd, fear actually writing the words “Welcome Home” could break her heart.The foster son they’re waiting for is part of a small, three-decade-old U.S. program for so-called unaccompanied refugee minors that has been halted by a series of new refugee bans and travel limits imposed by the Trump administration in the name of fighting terrorism.READ MORE: Donald Trump’s refugee ban given green light by Supreme CourtBy blocking the program, the U.S. travel bans have stranded more than 100 refugee children who were already matched to waiting American foster families. Without parents or other adult relatives, those kids are living on their own in countries of temporary refuge, in limbo while their U.S. foster parents hope for a court ruling that will allow the children to finish their journeys.Since the June day a refugee agency matched the Rooneys with their foster son, which turned out to be the same day of the first Supreme Court ruling barring him, “we have experienced this very unexpected ride of grief in our family,” says Rooney, a 39-year-old family therapist and mother of two from Brighton, a suburb of Detroit.WATCH: Trump claims victory after court upholds his travel ban

Meanwhile, the boy who fled his home country at 13 to avoid widespread forced military conscription of children continues to fend for himself on the streets in his temporary refuge in another African capital, with no phone or internet for the Rooneys to reach him to explain the delay.“There’s part of me that really hopes he knows a family wants him,” Tianna Rooney says.Since the 1980s, the program for orphaned refugee children has brought in more than 6,000 refugee children, including 203 last year.READ MORE: U.S. immigration officials abruptly leave Australian-run detention centre“These are kids on their own, and struggling to survive,” said Elizabeth Foydel, policy counsel with the International Refugee Assistance Project, a Washington, D.C., legal-aid group for refugees.“How long do you feel comfortable with your child not having a caregiver?” Foydel says she asks other Americans. “Trying to manage for themselves?”The program for orphaned refugee children from around the world is different from one started by the Obama administration in 2014 for Central American children fleeing a surge in violence there.

In the program for unaccompanied refugee children, kids eking out a living by themselves in a refugee camp or elsewhere must first come to the attention of a U.N. agency, which may choose to refer them for the U.S foster program, especially if the children are deemed to be particularly vulnerable wherever they are now. The children must then pass U.S. security screenings and other requirements, and win a match with an American foster family or group home.

But a series of Trump administration orders, and court rulings interpreting them, are now barring refugees with no close family in the United States. That requirement shuts out the refugee children in the foster program, who have no relatives they can turn to anywhere.

The child refugees newly blocked from waiting American foster families include five Ethiopian sisters, ages 9 to 16. The girls lost both parents in 2009, and have faced abuse alone in the war zone of neighboring South Sudan and in Sudanese cities, said Jessica Jones, policy counsel for the Baltimore-based Lutheran Immigration and Refugee Service. Along with the U.S. Conference of Catholic Bishops, the Lutherans are one of two U.S. groups running the program on behalf of the U.S. State Department.

Other waiting children include a 17-year-old couple originally from the Asian country of Myanmar and the baby they had together in a refugee camp, after fleeing attacks on their Rohingya religious minority in Myanmar.

In her home in another Detroit suburb, Sharon Martin, 64, has bought a crib for the young refugee family from Myanmar. But the children’s books she bought, Martin said, are really for her. “If they come, I can finally read to a child again,” Martin says.

Refugee workers say the family faces forced return to Myanmar if their U.S. arrangements fall through.

In San Francisco, meanwhile, web designer Julie Rajagopal and husband Mike Gougherty, a senior planner for a regional ferry system, are two of the lucky ones.

The 16-year-old boy they are fostering also fled a lifetime of forced military service in Eritrea, at 13. When he landed in March, a slight youth coming off the plane in an ill-made tracksuit, he was among the last refugee foster children to make it into the U.S.

Rajagopal, 35, often had stayed up through the night calling government workers and charity officials in the faraway African hub of Cairo to speed her new foster son’s paperwork.

On a clear day this summer, the teen strolled with the couple at a park overlooking San Francisco. In the city’s hip Mission District, he blended seamlessly in a red sweater and shoes he carefully matched himself, and jeans he insisted on lovingly ironing with each wear.

Meanwhile, in Brighton, the Rooneys and their 10- and 12-year-old sons stack new socks and T-shirts in the bedroom they’ve set aside for the boy they nicknamed “Five,” meaning the eagerly awaited fifth member of their family.

Tianna Rooney recently got out the poster board, thinking to work on the welcome sign. After a concerned look from her husband, she put it away.

“We want to think positive thoughts” that their foster son will come safely, Todd Rooney said. “But without endangering ourselves. Without setting ourselves up for a heartache.”
