Hi
I'm not qualified to help you but I've just recently completed my 14 year application so have some recent experience. It's a pity you can't afford to use a solicitor because my solicitor has been very helpful and very understanding, a long with giving me advice as to what UKBA are looking for.
This is the list my solicitor gave:
Life in UK Test Pass Notification
Documents relating to previous leave granted
Home Office correspondence for previous grants of leave
Payslips (n/a for you) and bank statements covering the past 14 years
Any contracts of employment (once again n/a)
All P60s (n/a)
Tenancy Agreements for the past 14 years
Utility bills/official correspondence received by you in the past 14 years
List of absences from the UK
Character references confirming you are person of good character I've highlighted this as my solicitor told me the more references I could get the better. Can you get references from your ex-lecturers at your uni?
Degree cert and other educational certificates.
Basically anything that can prove you have spent the last 14 years here and haven't left. In my case I sent documentation from the moment I arrived in this country, which was 16 years worth of docs.
With regards your medical records your doctor's surgery should be able to provide these or you should have a NHS medical card, send this with your application.
The thing that concerns me is the lack of passport because you need this. Maybe another poster can help.
http://www.ukba.homeoffice.gov.uk/sitec ... chapter18/ This link is invaluable to me. Scroll down to section 3.2 and this has everything they are looking for when considering any application. You will need to provide a covering letter so ensure to cover these points in relation to your personal situation, i.e. you have spent your formative years here therefore the only life you know is here in the UK!!
With regards to waiting times, I spoke to someone only yesterday and was told that if your application is straight forward with no complications you should receive a decision within 6 months. Complex applications you are looking for a wait of over 1 year. My attitude is it comes when it comes.
The deadline I think people are referring to is the directive given to the UKBA to have all legacy applications completed before July 2011. From what I've read there are major immigration reforms looming and I think this deadline along with the new citizenship rules may signal these. But I wouldn't wait if I was you!!!
Good luck
