A total of 54 LGBT and immigration advocacy groups are teaming up to make a renewed call on the Obama administration to take action on behalf of bi-national same-sex couples in the wake of the Supreme Court’s decision to take up litigation challenging DOMA. In a letter written Monday to President Obama and other administration officials, the groups call on the administration to place on hold the marriage-based green card applications for bi-national same-sex couples as observers await a final decision from the Supreme Court on DOMA’s constitutionality. “With the Supreme Court’s decision to rule on DOMA’s constitutionality, we will know by next June whether or not applications for lawful permanent residence for lesbian and gay spouses will ultimately be approvable,” the letter states. “Therefore, we are only asking that, in the interim, these applications be held for a period of a few months. Doing so will prevent extreme hardship to lesbian and gay immigrant families. By holding applications for lawful permanent residence in abeyance neither granting them nor denying them LGBT families can remain securely together in the U.S. until the Supreme Court issues its ruling next year.” Among the signatories of the letter are LGBT groups such as Immigration Equality, the Human Rights Campaign and the National Gay & Lesbian Task Force as well as the immigration groups such as the Mexican American Legal Defense & Educational Fund (MALDEF) and the National Council of La Raza.
