I am a non-EEA national unmarried with ILR that I received through Tier 2 route.
Regarding proving lawful residence in the UK during last 5 years:
I still have my passport that I was using throughout the period of my residence in the UK over the last five years. It contains all the stamps of entry into the UK however might miss some stamps for when leaving the UK (the European border forces wouldn't always bother stamping).Proof of living in the UK for 5 years if applying in your own right
If you are *not* married, or in a civil partnership with, a British citizen, you must have been in the UK for the past 5 years.
*If you are an EEA National,* you need to include letters from employers, educational establishments or other government departments, indicating your presence in the UK during the relevant 3- or 5-year period.
*If you are a Non-EEA National,* you need to include your passport to prove you have lived in the UK for the relevant 3- or 5-year period.
If you do not have your passport or it was not stamped when you entered the UK, you need to include letters (for example, from your employer or government department) as proof.
Bank statements or household bills are not suitable proof you have been living in the UK.
I understand that the passport will be sufficient however I read on some forums that one also needs to provide other proofs like P60s, employer letters, council tax, etc etc. Is that really necessary?
Thanks
