WP Renewal

Thank you guys for my previous query...

Just wanted to seek your advise to understand the Belgium WP Renewal process;

I have recently obtained a WP (Blue Card) to work for a client having name printed on WP. My visa will expire on 30th Sep 2019.

Do i need to return to my home country to renew my WP or am I allowed to continue my processing from Belgium itself? What is a minimum duration for which visa get renewed ?

Please suggest...
