Difference in Eb2 and Eb3
WEll, At Labor Certification, It really does not matter for EB categories.
But your ETA 750 needs to be filled accordingly if you plan to apply for EB2 or EB3 at I 140 levels. Hence it does matter how you put the job description and experience while filing for Labor.
At labor, If your company has history of advertising for a job for last six months, with skills that match your skills, then you can apply under RIR category other wise you need to apply under Normal Category.
When you reach I 140 level, the Regional DEpt (in our case , VSC) will decide ifyour aplication qualifies for EB2 category or not. They may ask for more supporting documents.
Earlier, EB2 was faster in term sof processing, but nowdays EB2 and EB3 have same processing times. Hence, Now days, it may not matter for those categories.
In fact , many applications are now being filed under EB3 category as they seem to be getting processed faster as we can see based on the responses published here.
Anyways, Its time to wait for that lucky day when Labor will get cleared in NY SESA!!!! Last year, in OCT - NOV It used to take 1-3 months for clearance of Labor!!!
