Julia Preston explains why a coalition of gay and immigrant rights groups are lobbying the Obama administration as they await a June ruling on DOMA:
[The] groups urged the president to “hold in abeyance” cases currently under consideration by federal immigration authorities of United States citizens who are seeking permanent resident visas, known as green cards, for immigrants of the same sex they legally married.
Nine states recognize same-sex marriages. But for the time being, an administration official said, DOMA “remains in effect and the Executive Branch will continue to enforce it unless and until Congress repeals it or there a final judicial determination that it is unconstitutional.”
In October, the Department of Homeland Security issued new guidance on the "family relationship" status of gay couples, giving law enforcement agents a discretionary basis for declining to initiate or carry out deportation proceedings. The administration has also hinted that it would include same-sex couples in immigration reform, which Obama indicated he will push for in January. According to Williams Institute researchers (pdf), as of 2010, some 40,000 binational or dual non-citizen gay couples would stand to benefit from immigration policies currently available only to straight married couples, as would the more than 25,000 children of such couples.
