Spouse Visa Extension how to get Urgently in UK, If not then can Spouse Visa extension from India affect ILR timeline?

[yogesh24]

Hi,
I am British Citizen by Naturalisation, My wife is holding Partner/Spouse visa. My Wife's Visa is ending end of December. We are planning to go to India at mid of November to stay there for 2 months.

Q1. Is any fast way to get her Visa extension before 15th Nov?

Q2. If it is difficult to get Spouse Visa extension before mid of November then can we apply her Spouse visa extension from India?
Q3. Is that will affect her ILR Clock timeline, will ILR clock reset in that way?

Q4. What if My wife's Spouse Visa extension we apply from India before the expiry of her current Spouse visa ending in End of Dec? Will that also reset her ILT clock?

Looking forward for you responses and any guidance will be highly appreciated.

Thanks,
Yogi
