My H1B dropbox appointment was on 28 Nov at Chennai VAC and on 1 Dec I saw that my application status was changed to "Application received" but since then there has been no further update. There have been floods in Chennai during the week of Dec 4-8, so I am assuming that is impacting the timeline. Does anyone know what is the typical timeline to getting the passport ready for pickup after drop off? My return tickets are for 25 Dec. At what point should i think about delaying my return?
