Naturalisation - No stamp when i came back to the UK from ireland

Hi everyone, I didn't get stamp on my passport when I came back to the UK from Ireland in 2014 January, since it's common travel zone, no passport required.

Now I'm applying for citizenship, I only have bank statement of 2014 and flight booking information. I don't know if It's enough to be proof? instead of The missing stamp, which is to proof the first day of five years period.


I don't have boarding pass, or any government official letter.

I know that there are a few people have discussed this, but could please anyone share if your application is successful, without any problem? So I don't need to wait until 2020 January, to be able to prove 2015 January entry.

I was in the UK 2014 January-December
2015 January to 2017 October, ilr granted from 2017 August.
2017 November to present 2019 January
I am only two months absent from the UK in five years and always here in one year.

I'd really appreciate your help!!
Regards,

The missing stamp was meant to prove the first Day of five years period.

When I applied for ILR, 10 years route, I didn't proof it, but I had a solicitor that time. This time I apply for it myself,

I am a non-eea, going to applying for citizenship online,

I have documents ready:
Passport,
BRP card,
My UK degree,
Life in the UK pass,
Two referees signature,

Work employment history - 3 years p45, p60
Additional I have recent 6 months bank statement,
2014 flight booking information, a whole year bank statement.

I hope it's sufficient?
