(CNN) -- Valera remembered being left in the Russian snow. How he lost his lower arms and some of his toes, he wasn't always sure. At times, he said he was in a fire. The truth of what the 14-year-old experienced in his early years, no one will ever know.





The orphanage where he lives said Valera was abandoned as a small child at a hospital in St. Petersburg, Russia. He had gangrene, the result of meningitis and an infection, which forced amputations. He was released to the orphanage in Nizhny Lomov, where he's waited nine years for parents and a home to call his own.





On Saturday, Stephen Jack and his wife, Christine, will leave their Goldsboro, North Carolina, home to fly to Russia, the final step in a 15-month journey they hope will give the boy what he's always wanted.





"Having never seen him and only knowing a little bit about him, I still feel attached to that child," said Jack, 53, who already has six children, four of them adopted. "I understand he can talk his way into your heart and mind in no time. When the world is opened up for him, who knows what his capabilities and possibilities are? ... If all goes well, on the 21st he becomes my son."





It is a trip the Jacks will take with trepidation.





The actions Thursday of a Tennessee woman who put her adopted 7-year-old son on a plane and returned him to Russia, saying he was violent and that officials misled her family, puts Americans in the process of adopting from Russia on edge. Officials in Moscow have threatened to suspend all American adoptions and the Jacks face a two-week process involving a court appearance and loads of paperwork before they can fly home with Valera.





"What this woman did to us is put us on pins and needles," Jack said. "My wife has been beside herself, and I'd be lying if I said I wasn't concerned."





The adoptions of about 3,000 Russian children by Americans are in progress, according to Tom DiFilipo, president of the Joint Council on International Children's Services, an advocacy group for children in need of families. Russia is the second country this year, after Haiti, in which adoptions have been thrown into a tailspin.





No suspension has been announced, but mere talk of such a recommendation spawned a campaign on Monday by the council to galvanize the adoption community and child advocates. People are being encouraged to sign a letter to President Obama and Russian President Dmitry Medvedev (which will be presented to them Wednesday morning), post blogs and share videos about adoption successes.





"Our message is this is an isolated incident. The adoption system did not fail. What failed was the decision-making process of this adoptive mother," DiFilipo said. What Torry Hansen of Tennessee did is "outrageous and indefensible, and not indicative of the average adoptive parent. One-hundred-thousand people adopt every year. I don't know of another case like this."





The case has rocked the adoption community.





"I talked to parents yesterday, and they're just devastated," said Deborah Gray, a child and family therapist, trainer and author, based in Seattle, Washington, who has 20-plus-years experience working on attachment, trauma and grief issues.





"It makes it seem like these kids are defective, that adoption itself is not a permanent status. ... It's a public embarrassment," she said. "The vast majority of families are enriched by adoption. To have this kind of approach is really off the wall. I can't understand why it would have gotten to this point."





Adoptive parents can feel overwhelmed during transition





She and other advocates said they wish Hansen had reached out for assistance and tapped services available for parents before shipping the child back to Russia after six months.





"There are so many services that were available to her. She could have contacted FRUA [Families for Russian and Ukrainian Adoption] which is a
