@GuitarCenter: Thank you for the response. I just wanted to know whether it creates problem showing elder brother in parents relationship document whom i didnt show before.  I am glad you had the same type of case. I think showing my elder brother will tie family bonds in the home country. They can say they have son and grand children in Nepal. Most importantly the VO will ask .. who will take care of your property and business when you are in usa? so .. they can say my son will take care.
