Topic: I-130 application form

Hi I am filling out an I-130 to petition for my mother to obtain a green card. I am a US citizen and my mother is a British citizen. She lived and worked in US from 1988-2006 but had to go back to UK for personal reasons therefore making her green card invalid. I need some help on a couple of questions please. Part 4 question 1) Alien Registration number if any Do I put her non-valid A-number ? Part 4 question 10) has anyone ever filed a petition for the beneficiary ? Do I say yes due to her having a previous green card ? Thank you jtuk62
