To be more specific...if your wife had filed for k-3 visa for you (immigrant visa for spouse...not a fiancee) the it was a concrete matter...
But still there another way of thinking that........
It's the girl who....................... decided which type of visa to apply...you just gave her the docs wanted and you may not necessarily be conversant with the laws and regulations!!
Engagement wasn't done before marriage and direct marriage was performed....that's OK........and it was wife's idea probably to do engagement after name sake for a photograph........And more importantly it wasn't performed with anyother person but within the same couple....to get a visa early for the simple reason that K-3 visa takes years to obtain (even 5-7 years now a days) and k-1 Visa was more quicker as per the opinion of the girl/wife (always refer her as wife)
A married couple can get married again and again with each other...or get engaged again and again with each other....that's not breaking any law!!!
..In India there is a ritual in some part of India to re-perform marriage ceremony to the same couple!!!... and wish the couple long life ...........after 25/50 years of their marriage.....and also a suvarna-chandi..tula(weighing the couple with silver or gold and donating it)...it's a ritual....It dosn't say that
You weren't aware whether you both were to go back or not after marriage...it was decided after marriage!!!
You both did the ceremony with intension to marry....and it was not like a TV soap shooting/drama of marriage incident in the serial!!!!
There can be error in the rituals but it doesn't invalidate the ceremony...because the intension, was very much existant to get married, by the both adults parties, and they both did so.....and registration isn't mandatory to selemnise a marriage.... attempts to deny occurance of marriage by...Negating a marriage on technicalities is struck OFF by Indian Courts many a number of time and too with very harsh comments against a party claiming absence of marriage...because it's just not a child's play and it a very serious activity by adults and not to be taken lightly ................
in rural india people get married in home....pandals put up in the open space in front of house...or in mohalla......
Registration's just a facility to put it on govt records formally.......
You said ::: kanya daan was done...and mangal sutra was tied in front of relatives...its a sufficient ritual for Hindu marriage.......
You may have erred in asking for a wrong visa...you may be rejected in the K-1 application....but that doesn't mean that existance of your marriage is also de-recognised...
Only a competant Court, having proper jurisdiction, can bring you back to 'single' status.
Plead guilty in front of consular commision...for wrong visa application knowingly........ but bring these fact that marriage did exist and it's valued as sacrament in India.
Other party may or may not send you offer to file visa for K-3...but in any case the other party also can't apply for k-1 or k-3 visa unless this marriage is legally broken
