No bickering guy's,
The reason for some 2002/2003 aprovals may be because of availble visa numbers for that financial year for a perticular category of cases.

A. STATUTORY NUMBERS
1. This bulletin summarizes the availability of immigrant numbers during June. Consular officers are required to report to the Department of State documentarily qualified applicants for numerically limited visas; the Bureau of Citizenship and Immigration Services in the Department of Homeland Security reports applicants for adjustment of status. Allocations were made, to the extent possible under the numerical limitations, for the demand received by June 6th in the chronological order of the reported priority dates. If the demand could not be satisfied within the statutory or regulatory limits, the category or foreign state in which demand was excessive was deemed oversubscribed. The cut-off date for an oversubscribed category is the priority date of the first applicant who could not be reached within the numerical limits. Only applicants who have a priority date earlier than the cut-off date may be allotted a number. Immediately that it becomes necessary during the monthly allocation process to retrogress a cut-off date, supplemental requests for numbers will be honored only if the priority date falls within the new cut-off date.
2. Section 201 of the Immigration and Nationality Act (INA) sets an annual minimum family-sponsored preference limit of 226,000. The worldwide level for annual employment-based preference immigrants is at least 140,000 . Section 202 prescribes that the per-country limit for preference immigrants is set at 7% of the total annual family-sponsored and employment-based preference limits, i.e., 25,620. The dependent area limit is set at 2%, or 7,320
