Income needed to sponsor family members

[stripedbass]

I am a naturalized American. Two years ago I petitioned for my mother and sister. My mother should be coming soon. My sister will take many years to come since she is over 21. However, I would like to petition for my other 2 sisters.

How much income do I need to show I have in order to petition for my other 2 sister (they are both of over 21)? Or do I not need to show my income until they are about to come?

I am single and don't have any kids of my own.

You don't have to show the income at the time of filing the petition. It is required at the time when your sister is ready to receive visa (which is 10-12 years from now).
