Here is the link that has all the positions listed. Check pages 53 to 63

This is what my rough guess is..... generally we have two categories like Software Developers & Sr. Software Developer, Software Analyst & Sr. Software Analyst etc. and so one for most of the positions. Accounrding to the current RIR and NON-RIR I guess all non Senior positions qualify for EB-3 and most of the senior positions qualify for EB-2. But the above list does not have any thing like that. I guess it may not be a complete list or if it is, then do we have to select only from this list of the occupation codes?
THIS IS A VERY SERIOUS ISSUE FOR LOT OF IT GUYS....
I HOPE ATTORNEYS WILL COMMENT ON THIS ISSUE
