It is difficult to apply for a German visa now. Is it possible to enter from other countries?

No. A valid Schengen visa applied for from another country is legal to attempt to enter any Schengen Agreement member state (including Germany). This does not mean entry must be granted by German (or any other) border agents - it can be challenged or even denied for a number of reasons. , but not possible with a valid visa unless on some watch list. As the number of people applying for German visas continues to increase, coupled with the impact of the COVID-19 epidemic, the visa center's appointment resources have become even tighter and it is difficult to meet the needs of all applicants. In addition, incomplete or incorrect information from applicants will also result in failed appointments, further reducing the number of available visa appointments.
