The September 2015 Visa Bulletin has been released. The nice thing is that F2A immigrant visas, which is to say green cards for husbands, wives, spouses and unmarried children under 21 of Lawful Permanent Residents, is “only” backed up a year and a half. Such people who will be getting their visas in September had immigration petitions filed for them in March of last year. In August, they were interviewing people who filed in December 2013, so this is an encouraging sign.
