Need advice on career: VA or school???

I'm an LPN currently attending fairmont state. I'm taking the prereqs for the RN program and plan on applying in december. Well I just got called for an interview at the VA nursing in in clarksburg WV. This came out of the blue, I wasn't expecting this at all! So now I'm going to the interview and I don't know what to do if they offer me a position. The interview is for a FT permanet position, so I'd hate to turn down an opportunity to get on at the VA, but I really want to get my RN so bad. I'm not going to be satisfied with stopping my career at an LPN level, I want those initials RN behind my name. I really am at a loss, if i turn down a position but don't get into the RN program, I'll kick myself for turning it down, but If I accept a position and get into the program, I'll have to leave the position, I'm not turning down an invite into fairmont's RN program, no way! So any advice on this situation???? I really don't know if there is a solution, I think I'm just going to have to see what life hands me. But Im praying for the right path.
