Amul,
I did not say that Philippines would have low demand in FB. Philippines always use their FB allocation.
It's not technically correct to refer to EB3 Philippines as using ROW spillover.
Philippines are using visas within the overall 7% limit across FB and EB. Since they use their allocation for FB,it can be simplified to use of the 7% within EB.
Currently, the
estimate of available EB visas for FY2015 is 144,730.
7% of that represents 10,131 visas available to Philippines in EB categories. Use of less than that number (however many might be in a specific Category such as EB3) is not a violation of the 7% limit.
In FY2014, Philippines used 8,172 visas within EB, of which 5,685 were in EB3, when the 7% limit within EB was 10,517.
Since EB3 as a whole has a fixed limit, the ability of Philippines to use more than the prorated 7% amount in EB3 reduces the number available to ROW, but that cannot be described as FA from ROW to Philippines. The same is also true of Mexico, but has not been much of an issue since they started to share the same COD as ROW in FY2011.
For FY2015, Philippines might use something like the following in the other Categories (historical use plus allowing a higher number for EB2 this FY):
EB1 ----- 250
EB2 --- 3,000
EB4 ----- 250
EB5 ------- 5
Total - 3,505
That theoretically leaves 6,626 that Philippines could use in EB3 and stay within the 7% limit.
A large part of EB-P use is by RN and PT who Consular Process in Manila. The rapid movement of the COD has increased the numbers of qualified applicants and many older cases have probably now re-qualified with new employers (having originally lost their sponsor). This has led to a surge of demand from EB3-P and necessitated retrogression. The NVC figures have always shown a huge number of CP cases (over 29k in Nov 2014). It's been a matter of speculation as to how many might be "dead" or "abandoned" cases.
EB3-Mexico have previously seen a similar situation. In FY2008 they were Unavailable for the final quarter and in both FY2009 and FY2010 they were made Unavailable from May to September, having used 5,325, 4,566 and 7,740 visas respectively.
India will be the only candidate for Fall Across from ROW within EB3. India applicants have the earliest PD and it's unlikely there will be sufficient FA to India in FY2015 will cause them to reach even the COD of 01JAN05 set for Philippines in the June VB. If they do, then both Countries will start to share FA.
