One adoptee was only twelve months when she was taken in by a American couple during 1966.
Hailing from the Korean peninsula, her birth father was a member of the US armed forces, who returned home shortly after Shirley was born.
"He abandoned us, is the nicest way I can express it," states Shirley, now 61.
Approximately one year later, Shirley was welcomed into the home of a US couple, who brought her to the Lone Star State.
An American Upbringing
She was raised living a life similar to those of most American youths.
"I lived and breathed and found mischief like many American teenagers during the eighties. I'm a child of the 80s," Shirley recalls.
Shirley had children, got married and worked as a music instructor.
Life carried on for decades with no reason to question her US citizenship.
But then in 2012, her world came crashing down.
Discovering Non-Citizen Status
She lost her government identification and needed a replacement.
But when she went to her local Social Security office, Shirley was told she had to demonstrate her legal standing in the country.
"I experienced an emotional collapse upon discovering I wasn't a citizen," she explains.
Widespread Problem
Shirley is not alone. Estimates of how many US adopted individuals lack citizenship vary between thousands to tens of thousands.
Numerous adoptees have been deported to their nations of origin in the past decade, according to adoptee rights organizations.
Another Story
Another woman, who requested anonymity for concern about attracting the attention of government officials, was adopted by an US pair from Iran in 1973 when she was just a toddler.
"I settled into my existence, always understanding that I was a US national. That was what I learned. I still believe that today," she states.
Legal Background
Over many years, international adoptions authorized through courts and government agencies did not automatically guarantee US citizenship.
The Children's Citizenship Law of 2000 created progress in addressing this issue, providing immediate citizenship to international adoptees.
Current Fears
These concerns for adopted individuals and their families have risen even further since shifts in administration.
Adoptee rights groups say they have been flooded with requests for help and some adoptees have disappeared from public view.
"Following political outcomes came in, it started to really cascade with requests for help," said a legal professional specializing in adoption law.
Stateless Feeling
"At the end of the day, authorities aren't concerned about your personal history. They don't care that your presence is lawful and it's just a paperwork error," she said.
"I frequently explain this one single piece of paper has fundamentally damaged my life," she said.
"As far as I'm concerned right now, I feel without a country."
Potential Solution
Although these individuals being in legal uncertainty for decades, attorneys believe it is simply a matter of legislative action that should gain bipartisan support from across the political spectrum.
"This ought to be a straightforward fix: adopted children should be treated the same as their biological siblings of guardians who were American nationals at the time of birth," said an attorney.
Final Plea
The adoptee hopes she could meet with national leaders for a discussion, so she and similar individuals could share their experiences.
"I would request to please have some compassion. We aren't undocumented immigrants," she said.
"We were put on planes as little itty-bitty babies. Please listen to our story and please follow through with the promise that the United States gave each one of the children that were brought here: American citizenship."
