My apologies, you posted a request for a live phone call.
my sister is a divorcee and lives with my parents along with her kids, she is completely dependent on my parents and has no source of income. Is there a immigration category to include my sister along with my parents' GC application that considers the fact she is a divorcee completely dependent on parents ?
No there is no special category for your sister. Your parents will have to immigrate and then petition her under Family Based 2B. The current wait for a priority date under that category for India is quite long. They are now processing petitions filed 15NOV08.
One alternative you may want to consider is for your sister to come here to school as a student on an F1 before you file the I-130 for your parents. She could remain in the US as a student, you petition your parents and they immigrate and then file for her while she is here and she continues in school and then OPT and a H1B job while waiting to get a current priority date.
I suggest she does this before you file for your parents since she is living with them and that would be her compelling tie to India that would show her intent to return when she completes her education.
