"The China-mainland born Employment Third and Third Other Workers cut-off dates have advanced for the month of August, and could do so again for September. There are two reasons for this advance after the retrogression of the cut-off date earlier this summer: 1) The heavy demand by applicants with priority dates significantly (years) earlier than the previous cut-off date has declined during the past two months, and 2) declining number use in the Family preferences during May and June, combined with updated estimates of such number use through the end of the fiscal year, has resulted in availability of several hundred numbers for use in the China-mainland born Employment Third preference.
During the past two months, the India Employment Second preference cut-off date has advanced very rapidly based on the projected availability of "otherwise unused" numbers under the worldwide preference limit. It must not be assumed that this cut-off date will continue to advance at the same pace during the coming months. A cut-off date does not mean that everyone with a priority date before such cut-off date has already been processed to conclusion. It remains to be seen how heavy the demand for visa numbers by applicants will be in the coming months, and what the priority dates of such applicants may be. Heavy demand by applicants with priority dates significantly earlier than the established cut-off date is expected to materialize within the next several months, at which time the cut-off date is likely to retrogress significantly." - DOS, July 8, 2014.
