The Visa Bulletin provides updated priority date information for family-based and employment-based green cards.
Immigrants to the US are classified into two categories – those requiring placement on a waiting list and those not through their relationship to a US immediate relative. Further, there are numerical quotas on the green cards that require a priority date. If the number of applicants in a year is over the available visa numbers, those applicants are placed on a waiting list and are given a priority date, which estimates when an applicant would get a visa based on the number of previous applicants on the waiting list. Below are preference category information and visa allocations.
