Many bi-national couples with one spouse who's American are being forced to move abroad. Former Washington Blade editor, Chris Crain, has to live in exile. So does Glenn Greenwald:
Brazil was a military dictatorship until 1985. It has the largest Catholic population of any country in the world. And yet I’m able to obtain from the Brazilian government a permanent visa because my Brazilian partner’s government recognizes our relationship for immigration purposes, while the government of my supposedly “free,” liberty-loving country enacted a law explicitly barring such recognition.
If the ban on HIV-positive immigrants stays in place, I may be forced to relocate back to Europe as well at some point. My current waiver runs out next March. My marriage and family, of course, count for nothing in the eyes of the US government.
