Full-Time Jobs for foreigners

Hi Pedro!

I think that if you are going to go as a Japanese language student, you shouldn't look for job in factories. They are very time consuming and you won't be ab;e to do both at the same time.

You should look for job maybe as an english teacher, or a teacher in another language.
Taking care of kids is another option. Some companies have child care and they could sponsor a visa for you.
Maybe look for classes for children, be it english, or even programming classes... even if you don't know the subject, usually it is something you can learn within a couple of days to be able to teach the children because its very simple.

Kombini or Market usually require good Japanese skills. If you try that, make sure you already learned conversational Japanese.
