Can waiting time be waived ?

My name is shazia and i am 33 years old.My parents applied for me in 1996 for immigration when they were PR , I waited for 6 years when my case got approved but by then i was married and based on that the case was denied and i was asked to re-apply once one of my parents becomes US citizen. My question is that do i need to wait another 6 or 7 years after they apply for me or teh waiting period will be exempted..i need your help, thanks you
