The availability of visas per category is based on numerical limits established by law. Where a category is listed as “current”, any eligible beneficiary may proceed with the final stages of the green card process (in most cases, I-485 adjustment of status application) no matter what their priority date. Where a cutoff date is listed for a particular category, only a beneficiary with a priority date on or before the cutoff date may proceed with the final stages of the green card process. A priority date reflects the filing date of the first step toward a permanent residence.
