The members of the family abroad have to submit an application of family reunification at an Austrian Embassy.
If there is no Austrian Embassy in the country or origin or residence, the family has to reach an Austrian Embassy in another country. Here all Austrians Embassies are listed.
Usually an appointment at the embassy is required. Some embassies have an online calendar. Waiting time varies and sometimes can take up to several months.
Each person willing to come to Austria needs to reach personally the embassy, children included.
If due to the waiting period for an appointment at the embassy it is not possible to apply within the required 3 months (please check below), the application can be submitted also in writing. In this case, it is recommended to consult a qualified advisor.
