Q,
It is possible that people are delaying the Consular Interview, but that is probably still the case, so it evens out.
The pending numbers for I-526 mean there are more than enough applications for high approvals this FY.
The figures of 1,885 for FY2010 and 4,218 for FY2009 visa issuance on page 13 match exactly to the figures published by DOS on the Visa Statistics page
http://travel.state.gov/visa/statist...tics_1476.html. The earlier years don't match exactly, but close enough.
The 30% increase is on filings in HALF a year compared to a WHOLE year, although the dates given in the table on page 7 are actually only for a QUARTER of a year (10/01/2010 – 12/31/2010), so the underlying increase is far higher than 30%. e.g
110 in
all FY2010 versus
146 in Q1-Q2 FY2011. The actual underlying increase is actually 165%, not 33% as presented in the table.
I am not saying the figures WILL double, only that there is no underlying reason why they cannot. Clearly the numbers will be far higher than last year, although it still isn't a large number in the grand scheme of things.
PS I can't work out where your 2,480 came from, but your calculation would become 2,480*2.65 = 6,596. I would see it more as 1,855*2.65 = 4,916 but I think that is too high. Double the Q1-Q2 FY visa issuance of 2,129 would give an increase of 130% on the FY2010 figure of 1,885.
