This question already has an answer here:
I have a plan to attend academic conference in Romania and then take a short stay in Austria. Unfortunately, the Embassy of Romania in Thailand is temporarily closed and I have to go to Philippines for visa issuing instead. They also give me a link as the following
"Holders of Schengen valid visas with multiple entries may enter Romania and stay until the date of the validity of the Schengen visa. Further information available at: http://bangkok.mae.ro/en/node/871"
If I apply for multiple entry Schengen visa for Austria, but I will enter Romania first and go for Austria later. Would it be possible in this case? I have written email to ask Ministry of Foreign Affairs in Romania, but did not get any response for a while.
