Priority date=28 September 2001 Case=i-130 Category=f-4 Given interview & medical test

However long it takes for the priority date to become current. A september 28, 2001 priority date is not current for any country.

I recommend that you look at the Visa Bulletin that the US publishes each month. The easiest way to do that is on the internet. Put in the query "current visa bulletin." For most countries, the current priority date in the F4 category is May 22, 2001, which means that your priority date is not yet current, and might not be current for another 4 - 5 months or longer. If you look at the Visa Bulletin, however, you will see that the wait is even longer if you are from certain countries, and you have not mentioned which country you are from. Priority dates do not go forward at a predictable rate, which is why it makes sense to look at the Visa Bulletin once a month. The Embassy usually does not review your case until your priority date becomes current. At that point, they may ask for updated documents.

The time that it will take for that priority date to become current.
