US Employment Based Immigrant Visa Availability for Worldwide First, Second, Third Categories Retrogress

The 2019 August Visa Bulletin shows Employment Based Worldwide First, Second, Third categories retrogress and are not current.
These EB1, EB2, and EB3 categories are not expected to be current through the end of the 2019 fiscal year.
D. ESTABLISHMENT AND RETROGRESSION OF AUGUST EMPLOYMENT-BASED FINAL ACTION DATES
There has been a steadily increasing level of Employment applicant demand since late May for adjustment of status cases filed with U.S. Citizenship and Immigration Services, and there is no indication that this increase will end. Therefore, it has been necessary to establish or retrogress many of the August Final Action Dates in an effort to hold worldwide number use within the maximum allowed under the respective FY-2019 annual limits.
The implementation of the above mentioned dates is expected to be only a temporary issue. For October, the first month of fiscal year 2020, every effort will be made to return these final action dates to those which applied for July 2019.
