I see....thanks for the info! I did some research yesterday and found that it would actually be better for me to go to grad school and get a MS in tech writing as it's only 30 credits. I couldn't actually start the MS until Fall 2015, and I could start the BS in tech writing in January 2015, but I'd need around 45 credits to finish that, so I'd just be paying more money to slog through an extra semester of lower level classes to get a lower degree and finish at around the same time as I could the MS.
So all I have to do is take the GRE, get accepted into the MS program, hammer out the 30 credits in two semesters, and then I'll have the magic MS that should allow me to get the engineer visa which would allow me to do a broad range of IT work in Japan it seems. Passing the N2 exam in Dec 2015 wouldn't hurt either. This is all going to take a lot of money - I don't want to be working while I'm back in school. I better get crackin'!
