Hello,
I am already here in US and my Both Parents are permanent Residents. Is there a way they can sponsor me ? and how long does it take for me to get the GC and can I stay in US at that period??
Are you here legally?
Yes, I am working on my masters right now...
Since you are here legally, they can sponsor you if you are under 21 (Category F2A), or over 21 and unmarried (F2B). You can check the processing times here: http://travel.state.gov/visa/bulleti...etin_1360.html
When they become US Citizens, your category would move to F1.
