Thank you for your reply. I would have a follow-up question regarding this:
It occurred to me that question No 6 within the online application process specifically asks if the applicant holds other nationalities. Since I am holding a valid passport of another country I have mentioned my other passport here this time. However, this is the first time authorities learned about it because I don't think that I have mentioned it when I extended my study permit for the first time (which was 4 years ago, and I don't really remember). I was wondering if this may cause delay or even problems with the renewal of my actual study permit.
I am just a bit over-reacting right now, because the second passport has never been used for travel, or visa issues anywhere. It has not even any entry stamps.
Thanks to everyone for help, and y'all good luck out there!!
