I need help with an assignment in my Immigration law course.

Practitioner Lori has been asked to conduct an initial interview of the Coulter family to determine the immigration status of each of them. Sam Coulter, born in Trinidad, states he is a lawful permanent resident and has a Resident Alien card. Two years ago, Sam met Anne, who arrived in the United States from Trinidad as a visitor on a B-2 single entry visa to compete in an athletic event. Anne's I-94 Arrival Departure Record card shows she had permission to remain in the United States for six months, but she met Sam, fell in love, and never left. They recently married and now have one daughter, Sheri, born in the United States.

What documents would you use to determine or confirm each family member's immigration status?
