Schengen Germany visa rejected

Question

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?

Answer 1

The reason that was given means that at least one Schengen country considers you, personally, to be a threat. That's much more specific than "justification for the purpose and conditions ... was not reliable" or "intention to leave ... could not be ascertained." They believe that you match a person in a terrorist threat database or the like (e.g. a criminal database).

• It could be a mistaken identity. They think that there is a terrorist named Abdullah and they falsely believe that you are this person.
• It could be a misinterpreted action. You did something and they falsely believe that it ties you to a terrorist context.

Either way, a new application will not help until this is cleared up. As phoog mentioned in his comment, read the linked answer by Henning and get a lawyer.
