Worldwide: This cut-off date has been advanced extremely rapidly during the past seven months in an effort to generate new demand. As the rate of applicants who are able to have action on their cases finalized increases, it could have a significant impact on the cut-off date situation. The rapid forward movement of this cut-off date should not be expected to continue beyond February.
China: Expected to remain at the worldwide date
India: No forward movement
Mexico: Expected to remain at the worldwide date
Philippines: 3 to 6 weeks

The above projections for the Family and Employment categories are for what is likely to happen during each of the next few months based on current applicant demand patterns. Readers should never assume that recent trends in cut-off date movements are guaranteed for the future, or that "corrective" action will not be required at some point in an effort to maintain number use within the applicable annual limits. The determination of the actual monthly cut-off dates is subject to fluctuations in applicant demand and a number of other variables. Unless indicated, those categories with a "Current" projection will remain so for the foreseeable future.
