This question already has an answer here:
The embassy of Spain recently refused my tourist visa, saying:
one or more of members states consider you a threat to public policy, internal security, public health under article 2(21) of regulation (EC)no399/2016 Schengen barcode or international relations of one or more member states
Similarly my Schengen visa was refused by Germany, Hungary and Italy within the last year.
I am a 62 year-old Medical Doctor and have previously traveled to the United States, Australia, Canada, Brazil, South Africa, Japan, Russia, Singapore, Hongkong, Turkey and many more countries, but never to Schengen countries.
I was misguided by my travel agent and didn’t appeal any of them before the Schengen visa refusal.
How should I appeal now to clear myself to visit Schengen countries?
