So he got a little impatient and decided to call yesterday (2 days after apping). Spoke to a representative, who asked him some questions (name, SS#, address, etc.) to pull up his application. The representative then put him on hold as he told him he needs to connect him to the lending department. He then came back after a couple minutes and said "nevermind sir, you'll need to call back on Monday and speak to the verification department as they're closed on the weekends."
That's the update I have so far. Will keep you all posted after he calls the verification department tomorrow.
Wonder if they work NYE ? GL to your brother!
