Wow so I took my biometrics on August 8.

I hadn't been checking my status because I assumed it would take at least 2 months but today I got the 821d approval letter and it appears my i765 was also approved although it doesnt say card is under production.

My timeline is

Application received 6/22
Biometrics done 8/8
765 approved - 8/17 (card not under production yet)
821d approved - 8/22

Nebraska Service Center by the way
