Did my 7th extension (>50) at CW earlier this month. See picture below for confirming residence extracted from the CW / Immi Div 1 handout.
However - I DO NOT have a lease (and in lieu, provide copies of
1) owners ID card (signed),
2) copy of blue book for 'my' house,
signed by owner, and
3) copy of blue book for owners residence
signed by owner -
~ MAY NOT BE REQUIRED ~
4) TM30
Thus - there is room for submitting alternative 'proofs' despite the handout wording - best to confirm with CW first / before applying and also bring copies of "everything"
- i think you mean new extension (not visa) - if you use your "old" passport for the new extension - the extension will only be upto the date the passport expires. Hopefully you can get the new passport back in time for the new extension so you get a full year.
- you'll submit a complete copy of the current passport with submission - Check the application forms - ie you keep the passport (but once application is submitted it can not be used for travel). Not sure how VFS/HMPO arrange the logistics of getting the new passport (with embassy letter & passport cancelling) to you in CM - is it via the consulate.
I just got my new uk passport a week ago - HMPO / VFS in Trendy said upto 11 weeks - new passport returned and in hand by week 6. The embassy here has nothing to do with renewing passports it's all done thru VFS. (Except emergency travel doc')
Spent best part of 6 hrs yesterday at CW waiting for 5min to transfer my stamps / details over to new passport. Simple but time consuming.
Visa's (as in stickers) do not get transferred so you'd use both passports - extensions of stay (as in stamps) get transferred over.
Still confused if bank statements OR just updated bank book(s) since last extension are needed at CW to show the req'd financial have been met. Obviously just the updated bank book is must easier.
