aC21 case approved
My case has been approved on 23rd June. I did use AC21 portability in May 2006 and took full time position in Big company.
I never had any RFE in my entire process. My title when applied for GC in 2002 September was Programmer Analyst. When i changed my job it's Sr Lead programmer and also the responsiblities changed to lead role. The AC21 we sent shows the responsibilities are lead role and were different from previous one( few of them like design, support, coding etc were matching to my roles i mentioned in my original application).
Also there is so much diff in salary also(it's more than 50K higher than to my amount mentioned in original application when i filled).
I never had any issues and got approval on 23rd June. So just make sure that your salary is not going down than the original one. Also make sure at least few responsibilities matching( need not to match all). That's waht my lawyer suggested me.
Also i guess once you cross 180 days of I-140 approval your comapny can't revoke it(not sure just find out time frame) and they don't have control over it.
Before you use AC21 make sure that your I-140 is already approved atleast some time back.
