Hi Krish,
I spoke to IRS sometime last week and they are expecting the ITIN office to be open this week or the week after. They did understand that a lot like us are paranoid about the documents mailed in along with the ITIN/tax return. All we know for now is that the documents are in the building, probably in the mail-room, unopened. Hope we get it soon.
I had mailed in my kid's passport in the first week of March and I have no update ever since.
Regards,
Arun
