Just to update the post of what my reseached have told me.
First I will finnish University of Teesside and get my bachelor degree.
After that I will go home to Norway for 1 year and find a fulltime job and earn around:
170NOK-200NOK | £17-£20 | 3634JPY-4275JPY | 32$-38$ (pr.hour) I guess.
I will save the money and get enough money to enter:
yamasa for 2 years.
After that I would like to find out if there is a chance I can go back to Norway and start searching for a Game Company that would help me with a work visa.
If a company will suport me with a work visa I will hopfully go down again if I liked Japan after my two years.
Any options?
