document is completed correctly as well as check your passport (meaning you do not need to relinquish your passport to the home office) and they forward the documents on to the home office. All the information for ILR is here:http://www.ukba.homeoffice.gov.uk/s\\... I would however check to see if you meet the requirements to Naturalise as a British citizen, if you are eligible I would apply for this instead. As you will be doubling what you have to pay out if you later want to go on and naturalise and get your British passport. However in order to naturalise you have to meet the requirements including passing the life in the UK test (proof of certificate is required with the application). Have a look here for eligibility:http://www.ukba.homeoffice.g\\... Once you are naturalised and have attended a British Citizenship ceremony you are eligible to apply for a British passport. So it would be in your best interest to check if you need to pay out twice or three times.
