Good for them:

Tim Coco and Genesio Oliveira married in 2005, among the throngs who wed after same-sex marriage became legal in Massachusetts. But for nearly three years, they lived apart — Coco in Haverhill and Oliveira in his native Brazil—because federal law does not recognize their union. On Wednesday, Oliveira returned to Massachusetts for an emotional reunion after federal immigration officials took the rare step of granting him permission to stay for one year on humanitarian grounds, clearing the way for him to try again for legal residency. His return followed personal appeals by Senator John F. Kerry, US Attorney General Eric Holder, and Homeland Security Secretary Janet Napolitano on their behalf.

But what about the rest?

According to the 2000 US Census, some 35,000 same-sex couples include one US citizen and a partner who is not.
