I am a US citizen, wishing to apply GC for my sibling(married, citizen of China). I understand 2 methods:
1. Apply GC for my sibling directly using I130 (I believe this is Category 4th)
2. Apply GC for my parents, and then apply citizen for them, and finally my parents apply GC for my sibling (I believe this is Category 3rd)
I was told the 2nd method is a few years faster. But according to the visa bulletin, the current visa date is: 01JAN02 for 3rd category, 01JUN01 for 4th category, the difference is only 6months.
Is it a good idea that I use both methods, i.e. I submit I130 for my sibling now, also apply GC for my parents. Later on, if my parents got citizen very quickly and then use method 2 at that time?
Also got another question regarding the above link, it said "Second: Spouses and Children, and Unmarried Sons and Daughters of Permanent
Residents: 114,200, plus the number (if any) by which the worldwide family preference level exceeds 226,000, and any unused first preference numbers", so does that mean that my parent does not need to become a US citizen in order to apply GC for my sibling?
thanks a lot
