I drop-box my passport along with my wife passport for H1/H4 stamping at Delhi center on Wednesday, 28th Dec'2018.

My wife passport got home delivered with stamped H4 VISA on 5th Dec'2018 but mine still showing "Your passport is still with the US Embassy/Consulate" on CEAC website.

However, the status check to [email protected] says "There is no status update available for the passport number submitted.

Has any one had similar experience ?
