October 2013 Visa Bulletin is of special significance as it will be the first bulletin for Fiscal Year 2014.
October 2012 Visa Bulletin had 01 SEP 04 as cut-off date for EB2 India. September 2013 Visa Bulletin had date of 15 JUN 08.
Now, for EB2 India, I can think of 3 possible scenarios:
1. It stays the same 15 JUN 08 and starts moving in last quarter of FY 2014.
2. It moves back to some date, say, 01 MAR 05 and starts moving depending on the porting trends.
3. It moves back to 01 SEP 04 and starts moving depending on the porting trends.
First one will be the best case scenario. Second is the most likely. It totally depends on what strategy DOS wants to adopt next fiscal year. Over the past few years, they have different strategies. I believe they have settled on one like the scenario 2.
For EB3 India, I believe it will keep going forward. It should move at one or two weeks per visa bulletin. It will move at a faster pace if there is more porting from EB3 to EB2.
March 2005 has 2848 applicants as per July I-485 pending inventory data on EB3 India. This might be a significant number for EB2 India cut off date. The new updated inventory expected to release next month, should give better idea on pending data for EB3 and EB2 and porting.
