Detailed description
A foreign national who has been expelled, deported, or returned may not re-enter or stay in Germany until the entry and residence ban has expired due to the entry and residence ban that was issued at the same time. The entry and residence ban is limited in time upon issuance.
If you are subject to a ban on entry and residence, you can submit an application to have this decision reviewed. This means you can either re-enter the country earlier than originally scheduled or the ban can be lifted entirely.
To do so, you must submit an application to the authority that issued your entry and residence ban.
