You would need to show that your life circumstances have changed such that there is no probability of you

- overstaying your visa in the US
- seeking employment
- falling back onto public services (food stamps, medicaid, medi-Cal, public housing etc.)  
- committing crimes or terror here (that's an easy one) 

The way to show that is **a well-established life** in a country where you are lawfully present, which gives you high incentive to return to your life there, and also high disincentive to stay in the US.   DavidSupportsMonica has an excellent answer describing what that looks like. 


If you're still an itinerant free spirit, it ain't gonna happen.
