Help Please.

I was born in Bombay 1975 and entered UK in 1979 on my mother's passport which is stamped IDL no restrictions.
I don't have a birth certificate as I never had one and my parents have passed away.
I have lived in the UK for 39 years with no problems but cannot travel. Any advice please.

Seriously !! what were you doing since 1979? Did your parents have ILR or British citizenship when you came here?
What is your current passport/visa?

I don't think you can get any help without providing enough information for the gurus to help out. Good luck mate

I have never held a passport I came on my mother's passport and it's stamped her and 3 children Indefinite leave to remain without restrictions. I have done schooling and work but now most jobs ask for proof birth certificate or passport. I don't possess any.
