I601 Waiver of ground of inadmissibility--actual estimated time frame

[Djsim218]

Nebraska NVC received my husband's I601 on 3/16/2018. USCIS lists 10.5-13 months estimated processing time.

Submitted a case inquiry and was told on 5/14/19 the case had not been processed.

Is there anyone that has gone through this process recently and has a better timeframe?

Thanks in advance!
