You would notice that this ratio is rising steadily. Following factors will cause the rise.
- If there are more folks from China the ratio will likely rise, China has much higher filing in Eb2 proportionately.
- For people in EB3 before Jul 2007 it makes some sense and they have EAD / AP, for people after Jul 2007 its a must to be in EB2 to get anything.
I agree with Nishant's comment that EB3 cases after Jul 2007 are kind of rare, if at all there are some people they are converting to EB2 or atleast trying.
