I'm not sure about homeschooling in another language but what i would like to comment on is the accent issue...
I really don't understand why it hinders so many people and why it is such a big issue... sure if u can perfect it and its well within your capabilities to do so then do it but if not i don't see an accent as a problem at all ... I'd rather speak and read and write 5 languages with accents than only two native ones....
It is very adolescent in my opinion to judge someone based on their accent .... noone really cares about the accent at the end of the day if what you are saying is valuable
