Nikkah and special marriage act

Hello kindly help me to decide on the following situation I belongs to a Hindu family and Im getting married to a Muslim guy through nikkah ie after proper conversion. My parents accepted for this conversion by grace but with one condition without gazette notification since we don't wanted to change my original name in all documents. But the problem now is they insisting to get one and without gazette we can't do nikkah. Even we ready to give them affidavit they still asking gazette which creates lot of confusion. To avoid this now we ready to give gazzete and gonna do nikkah as per their wish with Muslim name also we would like to register a marriage in SMA as per my original name since we are moving abroad and their will be no problem with original name documents which make ease to get visa process simple. So is this right decision? Another problem is that mandatory to change all documents name after gazette notification or will in reflect in any passport and visa processing? Kindly suggest me on this as soon as possible
