The petition was approved while I was there does that make any difference? Also I have a sister that is a US Citizen can she file a petition for me?
It does make a big difference. You then have to get a substitute sponsor for an affidavit of support. But you still need to ask for a special permission to be admitted after your removal. Your sister can petition you but it will take no less than 8-10 years before you can get a green card.
OK, I understand, another thing is I got ban for 10 years there is any waiver I can apply to reduce the time? They did not barred me at the point that i cant t go back to America, I was deported at the first time for overstay in 2006 and 2007 for trying to reentry.
No. The only way you can reduce the time is if you apply for permission known as I-212, and it is granted. The main problem with that is that you need to show that you have a spouse, parent or child who is a US citizen or a green card holder who will suffer extreme hardship if you are not admitted. Even though your sister is a US citizen, she does not qualify.
Thank you for your help.
