@Tod ********

as i had done an 'extension of 1 year' last year, i do not fall in the original 90 days that could run out as you mentioned. I had called the immigration bureau, asking what i need to do next around May,2020 and they had mentioned i do not have to visit the district immigration office at that period. Do you suggest me to visit the immigration office too? Thank you!

Thank you very much for the info. I will visit the Ministry of Labour asap.
