My friend went to the USCIS approved doctor to have her medical exam done (I-639). She went with her son who is 14 years old. The doctor did not know if the mother should sign I-639 on behalf of the kid or a kid should sign by himself. The doctor states that a parent should sign the documents on behalf of the child if the child is under 18, but the lawyer is pretty sure that the child can sign I-639 because he is over 14 and if the USCIS can fingerprint the 14 year olds so they can sign the immigration forms too.
Do you know who is right?
Thanks a lot.
