How to apply B2 Vista for my dad?

I had applied my dad for 1-130, and got approved. But my dad changed his mind, so I didn't continue. BTW, he currently is in Beijing. Now I am trying to apply B2 for him since my mom got her green card last year and still staying with me. My question is beside DS-160, what else do I need to prepare? Do I need invitation letter, financial support? Thanks
