An entry ban under section 53 FPG may follow a final conviction; duration and admissibility depend on the sentence and personal circumstances.
Section 53 FPG authorises the authority to impose an entry ban on third-country nationals where certain conditions are met. A conviction to a custodial sentence of one year or more can justify a ban of up to five years; for more serious offences longer bans are possible. The proportionality of the measure and its compatibility with Article 8 ECHR must be examined.
What to do now: First, clarify the exact sentence and ground of conviction with a lawyer, as these determine the duration and admissibility of the entry ban. Second, document family and social ties in Austria since these affect proportionality. Third, have the authority's decision carefully reviewed and observe the appeal deadlines.
