New passport, need to renew ILR

I've had my ILR (spouse visa) for 7 years. I just renewed my US passport, so what do I do now to get my ILR stamp transferred to my new passport? I had a quick search, but couldn't find a useful website. I found plenty of info about applying for ILR, but nothing about getting the stamp renewed in a new passport. Any info will be helpful... websites, applications, costs, etc...

Thanks,
Skyla

Scroll down to find form NTLTOC- that's the one you need.

Note that you don't have to transfer your ILR- you can continue to travel with it in the old passport if you carry both passports with you when you travel.  But if you wish to transfer it for convenience, then fill out the NTLTOC form and send it in - it'll cost you £160.

Cool! Thanks for the quick reply. At the moment, I don't see the point in transferring it. I'm going home for either TG or Xmas, so I'll just take both passports. If they give me any hassle, I'll transer it for next time.

Thanks again!
