Critically ill British baby Charlie Gard was granted permanent resident status in the U.S. on Tuesday so he can receive experimental treatment for his rare medical illness, The Telegraph reported.
The 11-month-old suffers from a rare genetic disease called mitochondrial DNA depletion syndrome, which weakens the muscles and creates organ dysfunction. The baby has been on life support at a children's hospital in London since October.
The baby was able to obtain resident status after Congress passed an amendment on Tuesday.
Charlie's parents have been fighting in court to keep their son on life support even though some doctors claimed in court that additional treatment was unlikely to work.
Dr. Michio Hirano, a neuroscientist from Columbia University in New York, recently flew to London to examine the baby's condition in a attempt to convince a judge that treatment in the U.S may be effective.
The doctor told the judges that the nucleoside therapy has a 10 percent chance of improving Charlie's condition.
