It's moving so fast, I have no idea if this was answered. Forgive me if it has been.
I am a legal resident of the USA, I'm a Legal Alien, as is my daughter. We have had to go to the DHS building and have had our fingerprints, palmprints, photos and handwriting samples taken. I have a Green Card, as does my daughter, but my son was born here and is automatically a US Citizen. It can be...difficult...going through airport security, especially when my son was too young to go by himself. Trust me. Every.single.aspect. of my life, my daughter's life, and Hannah's and her family's life, is 100% documented by Homeland Security. They do not mess about. If Hannah's fingerprints were found anywhere, they would on it. She, and her family, are on file. If the FBI is involved, they have every single detail of this family available asap.
This is not an assumption. My family is in the exact same position as Hannah's. They have EVERYTHING. They probably know more about my family history than I do. It is a very long, hard, complicated, and intrusive process to get a visa, after 9/11,
