The Visa Bulletin can be found on the US department of state’s website. Department of state issues a report and posts it at this website every month showing which family petition based visas and related green card applications can move forward. department of state reports to the public which petitions they are working on at this time and the dates those petitions were filed. This gives people awaiting their visas to come to u.s. an idea of when to expect their visa to be ready to be processed. The visa bulletin exists because Congress caps the number of green cards that can be issued each year in certain categories, which has created several backlogs.
