No problem at all. Just file Amended returns when she gets here.
ISL is not a high fraud consulate for IV categories. For non-immigrant visas eg, visit, student visas YES but Immigrant visas, especially marriage cases are pretty straight forward bcz of similar culture--traditional and religious marriages. The overwhelming issues at ISL are financial docs and the petitioner being being low income thus requiring joint sponsor. Any country that has high interfaith and inter-race marriages like the Philippines, Lebanon, Morroco, Thailand are more prone to marriage fraud.
