My partner and I decided to move back to her home country (The Netherlands) after spending a year in Portugal. I'm reading online that as a non-EU residence permit holder I'll need to deregister with AIMA and renounce my residence permit - is anyone familiar with this process and how long it takes?

Any recommendations on how to knock it out to ensure I have proof the process has been completed?

We already left the country so an in-person appointment won't be possible, and I'm a bit paranoid about sending a registered letter and just hoping to hear back from them... Would appreciate any guidance here!
