It expires June 12, but I have biometrics June 17. It was the soonest I could find.
And so what should I do about the application now? All of my evidence will have the dates before I submitted it just the printing date will be after since I have to reprint a few.
So like the pay slip will be dated before the date of application but the paper might say it was printed today for example.
Could I just write a letter saying that we had to reprint some of the evidence due to an accident?
Honestly, I don't quite know what the answer is here. All evidence really should have been printed and received before you submitted the online application, so that there would be no question or confusion about dates.
In regards to payslips and bank statements, what matters is the date the payslip was issued and the pay period it covers. Same with the bank statements - they must cover the same pay periods as the payslips, and show each payslip. So, as long as at least 6 months (or 12 months for Cat B) of the payslips and bank statements are dated before you submitted the online application, that part should be fine.
However, I'm not sure about the employer letter. Is it just the payslip verification letter from the previous employer that you are still waiting for? Is the letter from his current employer, confirming his employment details, dated before you submitted the online application?
