I am thinking to invite my parents to US again. They are trying it for second time. They tried 3 years back in a visitor visa when I was graduating . Now both me and my wife works as a software developer. I have few questions in mind as:

Should I sponsor them on solo?

Should me and my wife sponsor them jointly?

I have read in sajha from some friends that sponsorship means risk. The embassy will think we can afford to keep them here.
