Do we need annual / divorce / void our present marriage?

I m from gujrat, i got remarry in 2016, (me n my husband belong to Hindu religion), when i got remarry i had "deed of divorce", my husband is from USA ,he is green card holder, after our marriage my husband file a petition for USA for me, but USCIS (US Immigration Dept) demanded for my decree , so i applied in court n i got a court decree, n i submitted court decree to USCIS, but after 3 months, USCIS denied my file / immigration petition , USCIS said that i was not legally eligible for remarry with my husband, because when i got remarry i had not court decree, My questions are: 1) Is our marriage considered legally valid in India? 2) Do we need t annul or void or divorce our current marriage? 3) What is the solution for us to be considered as legally valid married in India?
