F. SCHEDULE A VISA AVAILABILITY DURING FY-2007

A total of 50,000 numbers were provided for use in the Schedule A (EX) visa category which was established last May. Visa demand in this category is approaching that limit, and may require the establishment of a cut-off date as early as October. Once all 50,000 numbers have been made available under the current limitation, processing under this category will end.

This is nothing new, and has been discussed since the beginning of this year. It has been well documented here as well.
