With regard to entry and residence, the Schengen entry requirements for visa-exempt third-country nationals apply to British nationals. As long as no gainful employment is to be pursued, they do not require a visa for visits and/or business trips with a maximum duration of stay of 90 days within a period of 180 days. When crossing the border, however, they must carry the documents and evidence required for entry into the Schengen States, in particular a valid travel document and evidence of the purpose and circumstances of the intended stay. If entry is for the purpose of study or gainful employment, newly arriving British nationals also do not require a visa. However, after entering Germany, they must apply for a residence title at the foreigners authority at their future place of residence. If they wish to take up employment immediately after entering Germany before obtaining a residence title, they must apply for a visa allowing them to take up employment at the relevant German mission abroad before entering the country.
