assets and family ties dont give much bearing anymore on US visa application, based on experience, i have used those tactics in my interview back home and i was told by the consul that i can leave my properties and families (parents, grandparents, siblings, etc) anytime... same thing that a friend advised me, i dont need to have assets/properties to get a visa, it's on how well i can convince them that i will return after my visit...

best of luck!
