My mother in law (Russian national) has a Schengen visa issued by Austria. The itinerary says she is entering Germany initially then travels to Austria in a few hours and stays there as her main destination.
We would now like to change this to a direct Austrian entry. Am I right in assuming that there will be no problem at the border since, while we dropped the point-of-entry country, it is not the one that issued the visa and so it's fine to just enter Austria with an Austrian-issued visa?
A side question is, is it also OK to add another country (Italy) and stay there for a few days longer than Austria, thereby making Italy the main destination? Obviously still within the original visa validity time frame!
