Visitor visa for unmarried sister

[spathak]

I am planning to invite my 33 year old unmarried sister to spend sometime with me here in the USA. She is currently staying with my parents and teaching in a local school. I am willing to sponsor her visit. However she does not have a very high paying job nor does she have any property in her name. She is the only sibling I have and is taking care of my elderly parents back home. My parents do have property and some savings back home which they are willing to show if needed as ties. Will that help at all? What documents should she carry for her visa interview? what are her chances of getting the visa? Thanks!

It is difficult for young people to get visitors visa who are single, don't have high paying job and don't have good amount of property. Showing your parents' property does not help.
