Can I apply for tier 2 extension from India?

[docviv1]

I'm currently working in UK, and my tier 2 is going to expire on 19/10/12. Am still waiting for my new CoS, which hopefully I should be getting in next few days. Can I apply for extension of my visa from India as I was planning to go to India in a couple of weeks? Also, if my visa expires on 19/10/12, does that mean I have to leave the country by 19th or is there any grace period allowed?

1. Extension ( leave to remain) cannot be applied for from outside the UK. To apply (for EC) from Outside the UK your employer will need to assign you a restricted CoS.
2. If you overstay for more than 28 days, it may affect entry clearance application(s) in the future. And, you will have to mention any overstay (even if less than 28 days) in any application that asks for such information.

Thanks a lot. That was really helpful.
