Kathy and Marie live together. Eventually they would like to buy a house and settle in New England, but that’s not going happen anytime soon: Marie, who is from Argentina, is in this country on a work visa that will soon expire. She has to leave the United States within a year.
“A heterosexual couple wouldn’t have that problem,” says Nancy Naples, professor of sociology and women’s studies. “They would get married and apply for a green card.”
Since federal immigration laws do not recognize same-sex couples, Kathy and Marie will probably have to part ways, unless Marie stays here illegally.
The couple, like thousands of Americans with foreign-born, same-sex partners, face difficult choices. Immigrants who apply for U.S. residency based on family ties must be the parent, child, sibling or spouse of a U.S. citizen.
