I have a slight (big) concern about my PR application because of the WRS certificate/card. I based my application on qualifying 5 year period from 9/2013-9/2018, have all the P60 and P45 and all other documents necessary.
Now, in the online application form there is a question about whether or not I ever used to work for an employer in UK during the Accession period between 2009-2011. I answered this as 'yes' because I came to UK back in 2008. I have the original WRS card for my first employer because I worked for them for over 3 years, but I noticed that it says job start date in 2009 when in fact I started to work for them in 2008, the same is for the date of issue. It is dated to 2009. As I was 20 at that time, I probably missed the importance to register within the first month and registered when I found out that I had to be registered.
What do I do now...

Thank you so so much to anyone who have anything to say, even if it is not a positive one.
