I'm planning a trip to Europe this summer (Italy, Spain and Portugal) and will be using my travel document (Form I-571) that I have based on asylum from Syria. I had a visa appointment at the Spanish consulate today and was not able to submit the application as the officer mentioned that Spain does not recognize refugee/asylee travel documents.
This wikipedia page mentions that Spain accepts U.S. travel documents, however, I've read other sources that site the opposite such as this thread. Do you know which countries accept a travel document (with a Schengen visa) in 2019? I'd appreciate if you can include an official website, I'm having a hard time finding any.
