Well replying to the questions you have posted and analyzing your perception I feel that you are caught up in the modernization dilemma. There are some good aspect to it as well as bad. The theory of "turning back" applies. Meaning that once we move forward we always have to turn back and realize how far we have come. You ask that shouldn't the couples know each other better before they get married? Perhaps but don't forget there was a day when you knowing each other was not the rule of the game, you were not allowed have even the snapshot of each other. Now my question to you from the question that you pose is well was that reasonable? Well it seemed to work for centuries but we live in a different world now or do we? Turn back and ask yourself. Other general aspect of you view is basically you are looking way forward towards the future. We must take life as it comes to you and do things that you are capable of doing at that moment, yes there will struggles, hassles, good times as well as bad times but that is life that is the challenge that life offers you every step of the way, thinking about what you don't have control over is only going to make you weak physically, mentally and spiritually, therefore just concentrate on what you have control over right now and let things unfold. We have not seen the future and we will never see the future that is the risk we take and return depends on how you handle that risk. Or is it really? The other question that you posed was in a matter of few days just looking at the green card people get married, both of them are strangers. Well in my opinion that is what makes it interesting, life is an adventure, it is a journey not a destination you learn nuts and bolts of each other as you move along you can't stop thinking that what is going to happen since that is not in your control. Green card, no green card, be in Nepal or abroad in general might have some effect on the marriage proposal that is on the table, after I feel that generally people "security" as the priority to a relationship green card just assumes the role of this security as of right now, this is a phase and it will linger for few years and then it is gone, then new phase is going to start, may be citizenship or who knows Nepal is going to the economic powerhouse down the line and then people from Nepal will be the one going abroad and make their choice. You never know these are all the phases of life ..........
