Check your priority date on the visa bulletin – Each month, the Department of State publishes priority dates for Immigrant Visas available for family-preference categories and employment-based petitions. The priority is generally based on the date your petition was submitted.
Check processing times of applications and petitions filed with USCIS – USCIS posts their current processing times on most applications or petitions.
