temporary resident visa ?

[DML]

Okay, so we went to SMdA today, filed our paperwork, paid our fee. no problems. We are supposed to return next week for fingerprinting. Now, my question(s):

1) after the finger printing we have to return to get our visas. I thought they said 2-3 weeks, my husband thought they said 2-3 days. Which is it?

2) I know we are not supposed to leave the country for 30 days. is that from today (the day we began the visa process) or 30 days from when we receive our visas?

I ask these questions because my husband has a business trip to Ecuador in September.

Any and all info is appreciated
