Charlie Gard given legal permanent residence by Congress to seek treatment in U.S.

But legal sources said Charlie is the subject of a High Court order and it made no difference what passport he held.

And last Friday, the judge made it clear it would be illegal for Charlie to travel to America without his permission.

The parents’ barrister Grant Armstrong said the parents were of the view that legally it was up to the hospital to change its mind and allow Charlie to be transferred.
