Texas GN permit processing time?? Relocating, please help!

I was hoping that someone who has applied for approval from the Texas BON to take the NCLEX might be able to answer a few questions for me. I'm from Minnesota and will be graduating in December. I recently landed a GN intern position down in Dallas area I am now looking at the process to be licensed in Texas so I could work as a GN starting in Janurary. I was shocked that you are supposed to apply 120 prior to graduation!

I did the online application today and paid the $139. I requested a FBI fingerprint card as well. I called the Texas BON to ask if I would be able to clear the background check and be approved by Janurary 4th (if I followed all the steps promptly). She responded by saying there is no way to know. I called someone else and they said that same thing :/ How long does this approval process usually take from start to finish? If I took this job (which is my dream job) and relocated, is it likely I would be in a situation where I would have no GN permit? I would appreciate any responses!! I really don't want to move 1000 miles away if I am going to end up jobless...
