I got married in USA. I organized all my rituals in a temple and performed a short-cut version of traditional Nepali wedding with an assistance of a “puret baje”. But I would have enjoyed it more if it was to happen in Nepal surrounded by family, relatives and friends. So if it is feasible, I would suggest you to get married in Nepal. I can assure you that you would be pleased with this decision. Congratulations and good luck with your planning!!!
