i see but my number is EU15*** so i have no idea when i receive it, thank you so much for ur answer Simon, ur so kind
Yes it is correct - it could be as much as 6 ot 7 weeks before the interview - or perhaps just 4 weeks. The 2NL is actually an email - and the email tells you to check the Status check website where you saw your selected letter. There you will then see the appointment details.
