Anyone can fall in love with anyone else. When dating, it is perfectly fine to date someone from another country. If you want to date a woman from Austria, that is up to you. Only you can make that decision. It doesn’t depend upon where the person is from, but their character. If you are planning on trying to date or have a relationship with someone from Austria and it is going to be a long-distance relationship, you should prepare yourself for that.
Long-distance relationships can work, but they are difficult because you won’t live near them. You usually don’t do things with them. However, you can certainly date an Austrian woman and have a nice relationship. There may be a language barrier though since their official language is German.
