The U.S. Supreme Court announced a decision today legalizing same sex marriage throughout the United States. This is a constitutional right protected under the Equal Protection and Due Process clauses. Religious institutions, however, still have a first amendment right to advocate against same sex marriages.
The Constitution applies to all persons in the United States, citizens and non-citizens alike. The immigrant community is included in these protections and rights. With the decision announced today, Immigration benefits cannot be denied in any state on the basis of same-sex marriages.
