What is maximum number of days before my visa extension is due that I can make extension?

Hi, my 90 day extension (Ed visa) runs out on 28th October. What is the maximum number of days before the extension expires that I can apply for a new extension. Also, the same question for the 90 day address report, what is the maximum number of days before the 90 day address report is due that i could make the report.

Any advice much appreciated.

• For 1 year extensions they will allow applications within the last 30 (maybe 45) days, but I don't know if that applies to 90 days extensions too. It's best to ask at your local office.
• You can report within 15 days before the report is due if applying in person.
