Marrying a foreigner in india

Do not marry in India.

Marriage of Indian with a foreigner should be done under the Special Marriage Act,1954. Secondly the issue if an Iranian woman marry outside her country with a foreigner, the NOC will be required from her local Embassy in India, if they're not issuing her NOC the Marriage Officer may not marry you with her under the Special Marriage Act. As far her stay in India after marriage is concerned that may not be possible immediately after expiry of her visa, and more over the marriage under the Special Marriage Act require one month notice after which marriage possible her stay in India should be for longer period not for one month only. As far Muslim Sharia law marriage is concerned that too will require registration for visa and other purposes and Marriage Registrar there too will also seek NOC from her local Embassy in India. In all cases your marriage with her require expert lawyer to help you out not novice who can put you in more trouble than solving it.

ok Thanks a lot sir for ur valuable advice. apart from special marriage act, i can marry her under muslim sharia law ? too since we both are muslims(shes from Iran).( or we need to marry under both the above and have 2 certificates of our marriage- one from the muslim sharia law and other one from the special marriage act )

she easily gets a 60 days indian e-visa and can get married here in india within that 60 days, later we can extend her tourist visa to short visit visa or Xvisa through the FRRO with the proof of our marriage certificate or should i apply for her extension before the marriage through my invitation letter or personal undertaking? so she doesnt needs to leave the country . 

*After the marriage is done, she can stay in India and her Visa can be extended(on the basis of our marriage certificate) so she doesnt needs to leave the country. I cant risk her going back to iran after the marriage, because her parents may not agree for our marriage and may not leven et her come back to India
