I applied/submitted my passport for renewal of B1/B2 visa via drop box at DHL on Dec 14. It's already 11 business days and I'm yet to receive info to pick up my passport. The status has changed from "being at the embassy/consulate" to "There is no status update available for the passport number submitted" What does this mean?

Secondly, I applied for a visa for my mum for a visit/holiday. According to the info on the website, she will need a Tourism visa which is B2 as against B1/B2 since she's retired. Is this correct? If it's not, will I have to re-book her for a B1/B2? Her interview is on Jan 25.

I intend taking her with me on my next trip.
