Took 21 months for me. Stopped using it for the last 2 and paid it to 0 and they graduated me.
It becomes official when the new statement generates. You can try requesting a limit increase. If you get the number to call in, it didn't graduate. If you get the limit increase form, they still haven't caught up yet.
It took me 10 months. I used mine very heavily. I think my score went up in the last couple months after something got deleted from TU, so that may have played a role. Just be patient. Almost everyone in the Discover graduation thread has got a CLI to $2,000 upon graduation, and you will get the cash back match at the end of one year as well. I got mine in April and it wss a $250 cash back match. I still haven't paid Discoiver even a dime since i opened my card in 03/2018 and I have made over $500 total in cash back. You can also request that they switch you the the 5% cash back program, which will not affect your graduation or cash back match.
