Mines at Potomac currently. I-130 was actually approved in early May but due to USCIS telling me multiple times (from multiple different agents I'll add) that my 130 was forwarded to NVC, even the date it was sent. Contact NVC and they have no record of it, lawfirm says I don't need to submit I-824, tier 2 at USCIS finally says I have to submit I-824. Didn't get my receipt notice until July 28th that USCIS has received the I-824.
Yeah the process feels like a jail almost, lock you away even after they approved the I-130 already, which in all honesty, if USCIS did not know what to do with it, they should have sent an RFE and not approved the petition. But, without the I-824, they wouldn't get an extra $465 from people 🤷♂️.
Working with the Congress office currently.
