If your petition was previously denied based on DOMA section 3, USCIS will now reopen those applications for review. Please note, you will need to notify USCIS by March 31, 2014, if your I-130 was denied before February 23, 2011. Requesting to consider reopening your petition will be done at no charge, but fees to file an application will still apply.
Same-sex marriages will receive the same immigration benefits as those of opposite sex. The five year residence period for naturalization may be reduced to three years if you have been living in marital union with a U.S. citizen spouse the same way that applies for opposite sex spouses.
