Two girls ages 4 and 8 were reunited in Mexico with their deported migrant parents Monday, after the couple was allowed to offer testimony in custody hearings in Pennsylvania via Internet phone-and-image conferencing.

U.S. and Mexican lawyers for the couple say it is the first time they know of that a U.S. court has allowed testimony in a custody case to be made over the Web, using voice and image conferencing via a service like Skype.
