There are plenty of Nepali chelibetis married to Indian dudes (much to dismay of Nepali torilaures, I reckon). Why wouldn't your parents accept her? In most cases, cultural difference  - religion and caste in most cases,  is what plays as the barrier in a relationship. Since she's an Indian, you should be good to go. This will bring more good than bad, imho. Talk to your parents openly. Since you're already in the states, they might warm up to the idea. 


Also, pomegranates, really? I know you didn't mean to disrespect her but perhaps the mannerism could've been different. We don't need to know details about your raslila. 

That said, I don't think you're gonna get momo banaune bhanda as dowry since Indians don't do momos kyare.
