How long will it take for the date to be current for my I130 F1 category?

There are periods when the priority dates progress faster or slower than the actual time, mainly because the number of the applications filed at about the same time can be smaller or larger than usual, while the capacity of the system to process applications and issue visas remains relatively stable. However, over the years, these variations even out, and priority dates progress roughly in sync with the calendar. It means that, in your case, the priority date will become current in approximately 6 years and 9 months.
