Annulment or divorce?

Mumbai, 12.Jun.2017: I'm a female, residing in Mumbai since birth. I got engaged in Dec 2016 to a boy originally born and brought up in Mumbai but now working in Los Angeles. He's been working in the US since Feb 2015. We decided to first get married in court by May 2017 and then later by traditional Roman Catholic Church rites in Nov 2017, so that I could apply for an H4 dependent visa on his H1B visa, serve a 3 month notice at my current job and then move to the US immediately in Nov 2017. We got married under the Special Marriage Act, 1954 on 30-May-2017. We had earlier agreed that we should not consummate our marriage before the traditional church rites. Now, however, due to differences in temperaments, natures and mainly uncertainty shown by my husband when I'll be financially dependent on him from Nov 2017, I have now decided to not continue this court marriage or to marry as per traditional church rites in Nov 2017. I have decided to not quit my job. Please suggest a way forward for me to get out of the legally married status. I would prefer to get an annulment.
