A return before the entry ban expires must not be planned without a legal check.
Under Section 53 FPG, an entry ban instructs a third-country national not to enter or stay in the territory of the Member States for a specified period. A later wish to return does not remove that effect by itself.
Before travelling, check the complete decision, the period of validity and the exact scope of the measure. Entering despite an existing ban may create additional immigration consequences.
