Your selection "EU/EEA/Swiss | researcher | up to a maximum of 3 months" resulted in the following information:
No registration required
EU/EEA nationals and nationals of Switzerland are generally permitted to stay in the EU member countries for up to three months.
Entry requirements
If you have sufficient financial means to finance your stay in Austria and valid health insurance covering all the necessary costs, you only need a valid travel document (passport or identity card) to enter and become resident in Austria.
You have to carry your travel document at all times as proof that you are entitled to reside in Austria.
Insurance
Researchers who have a valid national health insurance in an EU country can obtain a European Health Insurance Card (EHIC) from their health insurance provider in their country of origin upon application.
Please note: As a rule, the back of the card must have an expiry date in order to use the EHIC. Simply placing stars in the expiry date field is not sufficient!
With this card you will have access to all medically necessary public health services in Austria (at the same conditions and the same costs). However, visits to doctors that are not due to acute complaints (e.g. medical check-ups) are not covered. We therefore recommend that you additionally take out a travel health insurance (also if you wish to have repatriation costs covered).
Working
EU/EEA and Swiss nationals are allowed to work in Austria in any kind of job. They do not need any official permit such as a work permit.
Renewal and change to another residence title
If you are staying in Austria for more than three months, you have to apply for a Registration certificate ("Anmeldebescheinigung") within four months.
After five years of lawful and uninterrupted residence in Austria you are entitled to permanent residence. A "certificate of permanent residence" can then be issued upon request.
Please note
You have to register within three working days of arrival in Austria with the registration office at your place of residence.
Attention: You do not need to register if you are staying in a tourist accommodation (e.g. hotel, guesthouse, campsite, private room, AirBnB) for a maximum of 2 months. Please ask the tourist accommodation if they hold a guest register (=Gästeverzeichnis). Otherwise registeration at the registration office is required!
For stays longer than two months, you must register at the registration office, even if you have entered your details in the guest register!
