Assuming your petition is open and an interview is scheduled, they will mail your passport via Hong Kong Post, it takes two to four day for delivery. You have to pay $25 postage upfront.

depends on what kind of visa you are applying. If it's a tourist/business visa, you'll know within the same day and the passport will be mailed back to you by registered mail in just a few days.
