Spec,
Agree. One of my friend with PD 2010 got lucky and has been able to file AOS, he's lucky because his son is turning 21 next year. I'm sure there are many such cases, and hence CO has done a commendable job by finding some way thru this murky system.
Visa consumption may have reached CO's expected levels already, but I strongly doubt if he wants to make May bulletin effective in April itself. And anyways, what's the need. If thru April month, CIS requests for excessive visa numbers for approvable cases, then he might say 'Nay' and report them on DD. Isn't it?
On the other hand, CIS CSR's might have busy time with Jan filers calling in to open SR's though.
Thanks
