A visa number is essentially your ticket to a green card. The U.S. has annual caps on how many green cards it issues in certain categories, and each green card requires an available visa number. When a visa number is allocated to you, it means there's a spot available and you can proceed with the final steps of getting your permanent residence.
Visa number availability is tracked through the Visa Bulletin. When the bulletin shows that your priority date is current for your category, it means a visa number is (or will soon be) available for you. Without an available visa number, your green card application can't be finalized — even if everything else is approved.
For immediate relatives of U.S. citizens, visa numbers are always available — no caps, no waiting. But for family preference categories and employment-based categories, the annual limits create backlogs. Some categories, especially for applicants from India, China, Mexico, and the Philippines, can have waits measured in decades.
