I am an American f4 immigrant. What does the priority date mean?

This refers to the date when you submitted your immigration application. Specifically, the US Immigration Bureau publishes the timetable of various types of immigrant visas once a month, and roughly estimates the interview date of each type of immigrant visa. The timetable of different types of immigrant visas is different. I helped you see the F4 timetable in September of 20 10, and now it's 200 1, 10, 15. That is to say, people who submitted F4 immigration applications before June, 2006, 5438+0, 65438+ 10, 15 have been or will be interviewed.
