No, the Austrian Job Seeker Visa is non-extendable and cannot be renewed. The Austrian Job seeker visa is only issued for 6 months, after which you can either get a job offer and switch to a Red-White-Red Card (RWR Card), or leave the country before the expiration of the visa if you do not get a job. While you cannot extend the Austrian Job Seeker Visa, you can, however, secure a job offer and apply for a residence permit (RWR Card), which allows you to remain in the country for an extended period of time.
