@pk I understand and will follow as you suggested.
For the "Reason you’re submitting Form W-7", I selected 2 options: e: Spouse of U.S. citizen/resident alien, and h: Other.
I believe I should not have selected h: Other. This, in my opinion, led to the rejection, since all other documents were as required (Passport, legal stay). Filling only option "e" this time in a fresh W-7.
Thank you so much for the detailed instructions.
