With 1 time a few days overstay, getting an ED visa is probably no problem?
What is the difference between a visa from a private language course that is supplying 8 month visa and a selfdefense visa of 1 year, except the length?
Both of them are will have the 3 month extending?
Any differences with the pro and cons?
You are able to do the same things with it? For example can you get a driving license (+make test) with both?
TLDR : Answer Summary
An ED visa can be obtained even with a previous overstay, and there is a notable difference in the lengths of stay and extensions offered for language course visas (8-9 months with extensions) versus self-defense or martial arts visas (up to 1 year with 90-day extension increments). Both permits allow for similar activities, including obtaining a driving license, yet the major factor is the intended duration of stay.
