How much time have your spent together in person, before and after the marriage. How many trips before and after?
The evidence you listed is all about efforts YOU made. Previously, they questioned HER intent, not yours. Yes, anything that made them think her intentions were primarily to get to the USA, will still be considered but your marriage and more time together in person will be mitigating factors. Are there some things about what SHE has done to show HER relationship is bona fide (on her part) that you haven't mentioned?
