221g White slip

Hello there

My mom got 221g white slip ( B2 visa)last February 2021 at Chennai location. They asked her to come back when the embassies resume regular operations and appear for an interview on any week day.
Is there anything we could do other than waiting? It’s over an year now and we haven’t heard back from embassy. Do we need to make an appointment again or just walk in when the embassies are open? Could some one please let me know?

First time B1/B2 stamping has not yet been opened, reason why you haven’t received update from consulate on the pending 221g.
You can contact consulate and follow-up.

Sure, will do! Thank you!
