Partially agreeing with above views I will add as under.
Being Punjabi I can feel ground reality as well.
You have tried to portray the girl as thoroughly innocent.
You have told that she was forced to marry. How forced/ allured / motivated / FALSE PROMISE? When forced/ allured / motivated / FALSE PROMISE? By who forced/ allured / motivated / FALSE PROMISE? Why forced/ allured / motivated / FALSE PROMISE?
Such marriages do happen aboard on price. I she was having legal status she is well expected to have sold that status to illegally entered boys. This is not the first such case.
See movies in Punjabi "рдЬрдЯреНрдЯ & рдЬреВрд▓рд┐рдпрдЯ" "рдЪрд▓ рдореЗрд░рд╛ рдкреБрддреНрдд" hindi movie "рдЖ рдЕрдм рд▓реМрдЯ рдЪрд▓реЗрдВ" all boys (Indian/Pakistani) are in search of "рдкрдХреНрдХреА рдХреБрдбреА" for marriage and willing to pay price (economic/moral) and do to pay price. Scholars have said рд╕рд╛рд╣рд┐рддреНрдп рд╕рдорд╛рдЬ рдХрд╛ рджрд░реНрдкрдг рд╣реЛрддрд╛ рд╣реИ.
Funny. She was forced/ allured / motivated / FALSE PROMISE to marry and not forced/ allured / motivated / FALSE PROMISE to disclose marriage to her parents. She did so. She is herself morally guilty for fooling her parents.
Given facts do not at all show any crime on the part of boy as far as marriage is concerned. The girl may be guilty of fraudulent marriage as per law of the country where she is.
You have stated FALSE PROMISE which itself raises a strong suspicion that she has not been paid price of marriage as promised.
You have also tried to hide the country where such thing has happened.
The Indian criminal law applies to all the Indian nationals whether in India or outside. You have not stated nationality of boy and girl.
You have also not stated whether parents of the boy in India are in abroad.
It may be difficult for some dowry demand accused to be called back on dowry demand because the action should be crime in that country also and dowry demand most probably is not a crime in any other country. However extortion is a crime in every country. If the person has committed crime in other country and the action is crime in both the countries then he can be extradited by long and tiresome process. Once brought in India he can only be charged for extortion as dory demand will not be ground of extradition. If his parents are in India and then demanding dowry then the can be charged of all the offences.
