This question already has an answer here:
I applied for the Schengen visa and it got rejected citing the reason:
One or more Member States consider that you pose a threat to the public order, internal security, public health Article 2 (21) of Regulation (EC) No 2016/399 (the Schengen Borders Code) or the international relations of one or more Member States.
1) I got the last Schengen visa from France and instead of entering France I made the first entry to Holland and came back from Holland itself. As my name is Abdullah, and I have seen in other articles that this name has some issues.
2) I had a visa issued by the German embassy in my old passport, which wasn't attached to my application as I only supplied the new passport.
Kindly guide me what should I do? I have one month to apply again. Shall I apply again and attach the old passport? Shall I provide clarification saying: I confess my mistake of having French visa and travelling to Holland?
