H1B, H4 Visa

I had my visa interview on the 13th (Friday!!) of January. I went to the US on an F1 a few years ago for my masters, got a job offer while on OPT and got the H1 approval.

VO: Good morning, how's it going?
Me: I'm doing well, how are you?
VO: Pretty good. *takes PP, DS160*
VO: So whom will you be working for?
Me: I'm working with Company AAA in the US right now; I'm transfering
over to an H1 from OPT.
VO: Where in the US will you be working?
Me: BBB.
VO: So whom will you work for when you go to BBB?
Me: Erm, Company AAA itself.
VO: *Looks confused*
VO: Ohhh okay okay you're working directly for Company AAA. Can you
hand me your petition?
Me: *slides over the H1B petition*
VO: *Leafs through the passport*
VO: I see you have an F1 for your Masters stamped here, did you
graduate from University ABC?
Me: Nope, I transfered over to University XYZ and I'm about to
graduate, I only have my thesis left.
VO: Why did you transfer?
Me: XYZ offered me a TA/RA and was more aligned towards my research interests.
VO: So when will you graduate from XYZ?
Me: In May, I have my enrollment verification with me.
Me: *ruffles through the folder, can't find it, begins to panic*
VO: Don't worry about it, sir. So do you work in the computer science
domain or the financial domain?
Me: I work in the computer science domain as a software engineer. We
write software for our financial domain.
VO: So you have a degree in computer science?
Me: Yes, I have a bachelors degree in engineering, majoring in computer science.
VO: *Nods, types on his computer, takes a stamp and stamps "Canceled
without Prejudice" on my F1 vsa. Reaches out to grab a white pamphlet*
VO: Sir, your visa is approved and will reach you within 7 days.
Please go through this pamphlet which contains your rights within the
US.
Me: Thanks! Have a great day!
VO: You too, sir. Good luck.
