Immigrant Visa Availability in the Coming Months
In the December Bulletin, the State Department notes that employment-based adjustment of status filings have steadily increased in recent weeks, warning that if this demand continues, Final Action Dates may be established as early as January 2020 for EB-2 and EB-3 categories that were previously current. In addition, if this demand continues, EB-1 will remain retrogressed in January. The State Department has previously stated it does not expect EB-1 Worldwide to become current before April 2020.
