Do we need to cancel our non-immigration O visa and ED visas before relocating permanently?

@Sooi **************

, you can't ever renew a visa (or an extension) inside or outside the country you get a new one every year

If you have stamps like this in your passport you are on an extension of stay.

AND

if you want to know the correct way to do it you should go cancel them at the immigration office by showing them the date you're leaving and they will give you a new stamp good until that date only

This is what an extension stamp looks like. (this one is for retirement) yours would be for taking care of your child here.

As long as you don't intend to come back here you could leave and they will run out BUT if you ever come back and want to get them again you will have a problem if you don't cancel these

If you are on extensions of stays from the immigration office yes the proper way is to go there and cancel them BEFORE you leave.

However you mention before we relocate to another country for good, meaning you would never come back here, and in that case just leave.

Visas dont need to be cancelled.
