Hi, everyone, pretty simple question, my annual retirement visa is due for renewal, the date of which is a Friday, not very convenient for me, would prefer to go on Monday, so, does the 7 days after and 10 days before window apply to this extension?

No

You could go before friday but not after,cheers

For a retirement extension, 0 days after, 30 days before is better. There are variations regionally. 

Rather what I thought, but no harm in checking. Thanks for the replies.

45 days before due date at some offices.
