How soon before my retirement visa expires can I apply for an extension?

@Alex ******

if the passport you are using to get your extension has more than 12 months validity then you will get a 12-month extension but if it has less than 12 months they will give you the amount that is left on your passport. They only care about the passport you turn up with at their office. When you get a new passport you will have to go to immigration to get your visa stamp transferred to the new passport but you won't get a new extension at that point until the old one runs out.

@David ********

You can apply already 2 month prior the expiration. The extension starts next day after expiry date.
