The five employment-based green-card categories

The U.S. employment-based green card system is divided into five preference categories under INA §203(b):

Each category has its own evidence standards, priority-date queue, and processing time. Total wait stacks two clocks: visa-bulletin priority dates from the State Department's monthly bulletin, plus USCIS adjudication time on I-140 / I-485, posted at egov.uscis.gov/processing-times.
