Can I sponsor my elder sister's B2 visitor visa?

[sandeep.saluja]

Can I sponsor my elder sister's B2 visitor visa? She is unmarried, working and not dependent on me.
My father is a senior citizen, so I want my sister to accompany him while traveling.
Is it a good option to schedule visa stamping appointment for my father and sister together?

please provide more details;

What is your visa status in US?
What abt your mom?
What is your sister's annual income roughly?
( to see if she can fund the trip herself)
Do you have any other siblings living with your dad besides your sis?
Has your sis or dad ever been denied a US visa before/
Does your sis have any history of foreign travel?
