Hi, I'm turning 21 next month and i'm a college student here in Vegas and I'm a US citizen. My aunt and my grandparents are helping me for my school finances. I want to petition my parents when i turn 21, is there any possibility that they'll be approved even i'm a working student? If I can petition them they can also help me to finish my college since my parents are still young they are both 38yrs old and my mom is a registered nurse who can assist me with my needs. If yes, how about my 17yrs old brother & my 15 yrs old sister? My parents and siblings are in the Philippines right now. Thanks
