I became a US citizen through marriage. I want to move my parents and my 18 year-old brother permanently to the US.
1. Do I have to file a separate I-130 application for each parent?
2. Can I include my little brother on my I-130 petition for one or both parents?
3. When the time comes, does each parent have to file a separate I-485 application?
4. If I cannot apply for my little brother as part of my mom or dad's I-130, can he wait until my parents adjust their status and then have them petition for him as an unmarried child under 21?
Any help would be appreciated.
