Thanks for the information! @littlerr.
Here's my situation: My work permit is valid from 31/8/2018 to 30/8/2020 and my first IRP registration was on 25/10/2018. Instead of a full year from the registration date, they only gave me a year based on the starting date of my work permit, so my current IRP will expire on 30/08/2019 (not 24/10/2019...I don't know if that's common but later I found my other colleagues got an entire year starting from their registration dates.)
If I make a renewal appointment two weeks before the expiry of my current registration (let's say on 16/08/2019) and the renewal lasts for one year, it will expire on 15/08/2020, leaving a short period uncovered (16/8/2020 - 30/8/2020). To work legally for the last two weeks of my work permit valid period, would I need to renew my IRP again in Aug 2020 just to cover the 2-week gap? That would mean another hassle of appointment booking and 300EUR extra ...
