I am an American with a Thai spouse, we currently live in Thailand. My parents have invited me to meet them in Austria in May. I will go for about a week, this is easy for me and I will buy a ticket soon.

I am currently wondering how difficult it would be to get my wife a visitors visa to accompany me. Are there any Austrians or any one else for that matter on the forum who might be versed in this topic and have any idea about the process/probability she would get approval to visit the country. Also,

Thanks in advance

Probably not very difficult. If you read the Schengen visa sticky thread you will get an idea of what is involved.
