USCIS urges those wishing to adjust their status to apply to change underlying basis
U.S. Citizenship and Immigration Services encourages eligible applicants to consider requesting to transfer the underlying basis of their adjustment of status application to the first (priority workers) or second (noncitizens in professions with advanced degrees or with exceptional ability) employment-based preference categories, because there is an exceptionally high number of employment-based immigrant visas available in these categories during this fiscal year (October 2021 through September 2022).
The overall employment-based annual limit for fiscal year 2022 is approximately twice as high as usual, because that limit includes all unused family-sponsored visa numbers from fiscal year 2021, which was approximately 140,000.
In addition, under the relevant statute, any visas not required in the fifth employment-based preference category are made available in the first employment-based preference category, and any visas not required in the first employment-based preference category are made available in the second employment-based preference category.
