Hi,
I have 4 half sisters (same mother) Mother was born in Texas. Met a Greek man, went to Greece and had 2 children.(2 children were born earlier in TX)
The 2 younger children, at one time, did have a social security card, but mother has since died and no papers or ss card, birth certificates can be located. The children want to come to the US and are of legal age to do so. How do we go about getting proper identification or other documents (over here in the US), how do we go about getting the proper papers in order to be able to allow them to come to the states? I live in Texas and they live in Athens Greece.

I hope I have relayed enough information, please email me with your responses or suggestions.
thank you
