Hi Navis:

I am no expert on it but I can give you my experience and opinion.

MY passport expired and I made a new one. To be on the safe side I sent them both passport with certified copies so they can return my passport soon. I am not from India and I think there is a issue of Indian Nationality and British Nationality, which I dont know.

Passportexpiration should not have any impact on your status here because you should have received a letter from home office too.  That letter give you the right to abode. Always keep that letter as safe as your passport.  If you travel keep that letter, old passport and a new passport. Hopefully, you won't need it once you get British passport.

In any case I suggest leave your option open and get a new passport(Indian) and then apply.  You will also need your passport for other reasons other than just travel.

With all new procedure it could even take a year(Hopefully not) and then Home Office can still reject(doubly hopefully not).  I will always have more then one option if I need to travel in emergency.

Hope this helps.

thanks Waheed, You are right. It is better to have more option. I just cleared my test , do you have any idea for how long this test certificate is valued for? because if i have to give my passport for renewal, it will take 2 months to get it back

Expiry of Test Certificate is supposed to be a million pound question but so far we don't have an answer.  I ask Home Office by e-mail but have not received the answer yet.  I don't think that you will have a problem in 2-3 months. I think best place to ask this question would be a test site where you took the test. Let me know if they can give you a specific answer and I will post it as soon as I have the answer from Home office.
